-util-linux 2.8:
+util-linux 2.9i:
+
+* fixed 2.9h typo in more
+* added -m: `Monday is 1st day' option to cal (Jean-Francois Bignolles)
+* changed PAM stuff in login.c (+- mjohnson)
+* added warning to cfdisk in case of multiple bootable partitions
+* added 2048-byte sector support in fdisk (Oliver Schaertel)
+
+util-linux 2.9h:
+
+* mount recognizes "uid=useruid" and "gid=usergid" in /etc/fstab.
+* documented the fact that "mount -t smb" will call /sbin/mount.smb.
+* mount gives clear error message when fstab does not end in newline.
+* swapon checks mode of file
+* cfdisk got a more specific exit status (Enrique Zanardi)
+
+util-linux 2.9g:
+
+* mount updates (locking, "users" keyword, "/etc/filesystems",
+ "proto" and "vers" options in nfsmount, ...)
+
+util-linux 2.9f:
+
+* made ul handle lines of arbitrary length (Scott Maxwell)
+* killed some C/H/S nonsense in fdisk
+* fixes for archs with unsigned char type (Ambrose Li)
+* fdisk fixes for power pc (Tom Rini)
+* added a define for NCURSES_CONST
+* fixes for list of signals in kill.c
+* fixes for user name length in last.c
+
+util-linux 2.9e:
+
+* added a forgotten declaration to login.c (Christian Oyarzun)
-WARNING: THE PROGRAMS IN THIS SUITE DO *NOT* SUPPORT SHADOW PASSWORD FILES!
- UNLESS YOU USE PAM.
+util-linux 2.9d:
-WARNING: THIS COLLECTION CONFLICTS WITH SYSTEM V INITTAB.
- UNLESS YOU CONFIGURE IT NOT TO.
+* fixed segfault in umount caused by Wilcox' patch (Steffen Zahn)
+* added lnz stuff to fdisk
-WARNING: USE GNU TAR -- OTHER TARS WILL FAIL SILENTLY!
+util-linux 2.9c:
-WARNING: DO *NOT* INSTALL WITHOUT THINKING.
+* refixed PAM stuff in login.c that was broken in 2.8.
-WARNING: The simpleinit and some other programs in this package are
- *NOT* System V compliant. These utilities are meant to be
- used by people who build their own systems. If you are not
- a wizard, do *NOT* blindly install these utilities: they could
- prevent you from logging into your system. Have a boot floppy
- ready, especially if you don't know what you are doing. It's a
- great way to learn though ;-)
+util-linux 2.9b:
+* split README into INSTALL and HISTORY
+* added a sentence to swapon.8
+* behaviour of write on non-ASCII fixed
+* hwclock adapted to survive a failing mktime()
-To install from source:
+util-linux 2.9a:
-1) Get source distribution (see the .lsm file for locations)
-2) Untar util-linux-2.8.tar.gz in /usr/src
-3) cd util-linux-2.8
-4) Edit MCONFIG
-5) make
-6) make install
-7) If you want to use simpleinit and agetty, then make softlinks from
- /sbin/init to simpleinit and from /sbin/getty to agetty, but make sure
- that your /etc/inittab is set up right (this is *NOT* the System V
- compatible init!), or you will be hosed. If you are using the SysV
- init and/or some other getty, they you can keep using those.
+* added an include to lib/my_reboot.c so that __GLIBC__ is defined
+* added setlocale() to login-utils/chfn.c
+* do not recompute MAIL in login-utils/login.c
+
+util-linux 2.9:
+
+HIGHLIGHTS for version 2.9:
+
+1) Removed programs:
+ - strings. There is a version in binutils.
+ - frag. (Moved to historic in 2.4, crept back in 2.5. Gone again.)
+1a) Not yet removed program:
+ - setfdprm. It also is in fdutils-5.2 (with an exceptionally
+ ugly man page).
+1b) Removed directory:
+ - bsd. (The routine getopt() is in libc. err() moved to lib.)
+2) Improvements:
+ - ddate has been fixed to count down to the new, right X-day
+ - look is now willing to search non-English dictionaries
+ (i.e., uses locale)
+ - cal now knows that Dutch day abbreviations have length 2 only
+ - mcookie does not block when no random stuff is available
+ - shutdown got a configuration file /etc/shutdown.conf
+ - fdisk now reads SGI disk labels (thanks to Andreas Neuper)
+ - mkswap now knows about new swap areas; mkswap.8 has been rewritten
+ - umount knows about umount2() and forced unmounting of nfs mounts
+ (however, I don't think it really works)
+ - mount is now willing to handle file names with embedded spaces
+ - mount can now mount things by UUID or volume name
+3) Uglifications:
+ - swap.h has been replaced by a private swap_constants.h since
+ <linux/swap.h> does not compile
+ - reboot has become a private routine, since libc5 and glibc2 conflict
+ - a mkminix-0.1 directory contains some patches to let mkfs.minix
+ work under DOS. (Untested.)
+4) Numerous other small changes.
+
+0xF) Send questions and/or patches to util-linux@math.uio.no
+
+util-linux 2.8:
HIGHLIGHTS for version 2.8:
-0a) It's been way to long since the last release. My fault.
-0b) NO PAM patches.
1) New programs:
- getopt(1) by Frodo Looijaard replaces the older bsd based version.
Keywords: Backward compatible, supports --long options.
1) Removed programs:
- chroot: is no longer in util-linux. Get it free with GNU sh-utils
- - frag:
- - lpcntl: This was removed in an earlier release (2.7) but I forgot to
- mention it.
- hostid: No-one could figure out the right way for this program to
work. Another hostid program is included in poeigl
(see the LSM, Primary-site: ftp.daimi.aau.dk /pub/linux/poe)
are encouraged to send patches.
3) rev now only limits linelength to memory capacity
4) dmesg now uses a buffer that matches the kernel buffer in size (8KB)
-0xF) Send questions and/or patches to util-linux@math.uio.no
util-linux 2.7:
converted to use terminfo (instead of termcap).
2) Removed progams:
- - clock: Dropped entierly. Use hwclock (included).
+ - clock: Dropped entirely. Use hwclock (included).
- sync: is in gnu fileutils.
- setserial: Is being maintained by Ted Ts'o, he recommends
setserial-2.12 (2.13 is bad luck)
- clear: Included in ncurses
- hostname, domainname, dnsdomainname: It's in net-utils.
+ - lpcntl.
3) Bugfixes, additions:
- cfdisk: A much improved version. All known bugs have been fixed.
ways to deal with this:
- Don't run rpcgen, the needed pre-generated sources are included
(nfsmount_xdr.c). You must hack mount/Makefile to do this.
- - Edit the source emited by rpcgen so it can compile. This is very
+ - Edit the source emitted by rpcgen so it can compile. This is very
simple if you know C.
- Disable the NFS parts of mount. You have to edit mount/Makefile
to do this.
- - Use some other rpcgen
+ - Use some other rpcgen.

-.Sh NAME
-.Nm getopt
-.Nd get option letter from argv
-.Sh SYNOPSIS
-.Fd #include <stdlib.h>
-.Vt extern char *optarg
-.Vt extern int optind
-.Vt extern int opterr
-.Ft int
-.Fn getopt "int argc" "char * const *argv" "const char *optstring"
-.Sh DESCRIPTION
-The
-.Fn getopt
-function gets
-the next
-.Em known
-option character from
-.Fa argv .
-An option character is
-.Em known
-if it has been specified in the string of accepted option characters,
-.Fa optstring .
-.Pp
-The option string
-.Fa optstring
-may contain the following characters; letters and
-letters followed by a colon to indicate an option argument
-is to follow. It does not matter to
-.Fn getopt
-if a following argument has leading white space.
-.Pp
-On return from
-.Fn getopt ,
-.Va optarg
-points to an option argument, if it is anticipated,
-and the variable
-.Va optind
-contains the index to the next
-.Fa argv
-argument for a subsequent call
-to
-.Fn getopt .
-.Pp
-The variable
-.Va opterr
-and
-.Va optind
-are both initialized to 1.
-In order to use
-.Fn getopt
-to evaluate multiple sets of arguments, or to evaluate a single set of
-arguments multiple times,
-.Va optind
-must be initialized to the number of argv entries to be skipped in each
-evaluation.
-.Pp
-The
-.Fn getopt
-function
-returns an
-.Dv EOF
-when the argument list is exhausted, or a non-recognized
-option is encountered.
-The interpretation of options in the argument list may be cancelled
-by the option
-.Ql --
-(double dash) which causes
-.Fn getopt
-to signal the end of argument processing and return an
-.Dv EOF .
-When all options have been processed (i.e., up to the first non-option
-argument),
-.Fn getopt
-returns
-.Dv EOF .
-.Sh DIAGNOSTICS
-If the
-.Fn getopt
-function encounters a character not found in the string
-.Va optarg
-or detects
-a missing option argument
-it writes error message
-.Ql ?
-to the
-.Em stderr .
-Setting
-.Va opterr
-to a zero will disable these error messages.
-.Sh EXAMPLE
-.Bd -literal -compact
-extern char *optarg;
-extern int optind;
-int bflag, ch, fd;
-
-bflag = 0;
-while ((ch = getopt(argc, argv, "bf:")) != EOF)
- switch(ch) {
- case 'b':
- bflag = 1;
- break;
- case 'f':
- if ((fd = open(optarg, O_RDONLY, 0)) < 0) {
- (void)fprintf(stderr,
- "myname: unable to read file %s.\en", optarg);
- exit(1) ;
- }
- break;
- case '?':
- default:
- usage();
-}
-argc -= optind;
-argv += optind;
-.Ed
-.Sh HISTORY
-The
-.Fn getopt
-function appeared
-.Bx 4.3 .
-.Sh BUGS
-Option arguments are allowed to begin with
-.Dq Li \- ;
-this is reasonable but
-reduces the amount of error checking possible.
-.Pp
-A single dash
-.Dq Li -
-may be specified as an character in
-.Fa optstring ,
-however it should
-.Em never
-have an argument associated with it.
-This allows
-.Fn getopt
-to be used with programs that expect
-.Dq Li -
-as an option flag.
-This practice is wrong, and should not be used in any current development.
-It is provided for backward compatibility
-.Em only .
-By default, a single dash causes
-.Fn getopt
-to return
-.Dv EOF .
-This is, we believe, compatible with System V.
-.Pp
-It is also possible to handle digits as option letters.
-This allows
-.Fn getopt
-to be used with programs that expect a number
-.Pq Dq Li \&-\&3
-as an option.
-This practice is wrong, and should not be used in any current development.
-It is provided for backward compatibility
-.Em only .
-The following code fragment works fairly well.
-.Bd -literal -offset indent
-int length;
-char *p;
-
-while ((c = getopt(argc, argv, "0123456789")) != EOF)
- switch (c) {
- case '0': case '1': case '2': case '3': case '4':
- case '5': case '6': case '7': case '8': case '9':
- p = argv[optind - 1];
- if (p[0] == '-' && p[1] == ch && !p[2])
- length = atoi(++p);
- else
- length = atoi(argv[optind] + 1);
- break;
- }

-.TH CFDISK 8 "25 April 1994" "The BOGUS Linux Release" "Linux Programmer's Manual"
-.SH NAME
-cfdisk \- Curses based disk partition table manipulator for Linux
-.SH SYNOPSIS
-.BI "cfdisk [ \-avz ] [ \-c " cylinders " ] [ \-h " heads " ]"
-.BI "[ \-s " sectors-per-track " ] [ -P " opt " ] [ " device " ]"
-.SH DESCRIPTION
-.B cfdisk
-is a curses based program for partitioning a hard disk drive. The
-.I device
-can be any one of the following:
-.sp
-.nf
-.RS
-/dev/hda [default]
-/dev/hdb
-/dev/sda
-/dev/sdb
-/dev/sdc
-/dev/sdd
-.RE
-.fi
-
-.B cfdisk
-first tries to read the geometry of the hard disk. If it fails, an
-error message is displayed and
-.B cfdisk
-exits. This should only happen when partitioning a SCSI drive on an
-adapter without a BIOS. To correct this problem, you can set the
-.IR cylinders ", " heads " and " sectors-per-track
-on the command line. Next,
-.B cfdisk
-tries to read the current partition table from the disk drive. If it
-is unable to figure out the partition table, an error is displayed and
-the program will exit. This might also be caused by incorrect
-geometry information, and can be overridden on the command line.
-Another way around this problem is with the
-.B \-z
-option. This will ignore the partition table on the disk.
-
-The main display is composed of four sections, from top to bottom: the
-header, the partitions, the command line and a warning line. The
-header contains the program name and version number followed by the
-disk drive and its geometry. The partitions section always displays
-the current partition table. The command line is the place where
-commands and text are entered. The available commands are usually
-displayed in brackets. The warning line is usually empty except when
-there is important information to be displayed. The current partition
-is highlighted with reverse video (or an arrow if the
-.B \-a
-option is given). All partition specific commands apply to the
-current partition.
-
-The format of the partition table in the partitions section is, from
-left to right: Name, Flags, Partition Type, Filesystem Type and Size.
-The name is the partition device name. The flags can be
-.IR Boot ,
-which designates a bootable partition or
-.IR NC ,
-which stands for "Not Compatible with DOS or OS/2". DOS, OS/2 and
-possibly other operating systems require the first sector of the first
-partition on the disk and all logical partitions to begin on the
-second head. This wastes the second through the last sector of the
-first track of the first head (the first sector is taken by the
-partition table itself).
-.B cfdisk
-allows you to recover these "lost" sectors with the maximize command
-.RB ( m ).
-.I Note:
-.BR fdisk (8)
-and some early versions of DOS create all partitions with the number
-of sectors already maximized. For more information, see the maximize
-command below. The partition type can be one of
-.IR Primary " or " Logical .
-For unallocated space on the drive, the partition type can also be
-.IR Pri/Log ,
-or empty (if the space is unusable). The filesystem type section
-displays the name of the filesystem used on the partition, if known.
-If it is unknown, then
-.I Unknown
-and the hex value of the filesystem type are displayed. A special
-case occurs when there are sections of the disk drive that cannot be
-used (because all of the primary partitions are used). When this is
-detected, the filesystem type is displayed as
-.IR Unusable .
-The size field displays the size of the partition in megabytes (by
-default). It can also display the size in sectors and cylinders (see
-the change units command below). If an asterisks
-.RB ( * )
-appears after the size, this means that the partition is not aligned
-on cylinder boundaries.
-.SH "DOS 6.x WARNING"
-
-The DOS 6.x FORMAT command looks for some information in the first
-sector of the data area of the partition, and treats this information
-as more reliable than the information in the partition table. DOS
-FORMAT expects DOS FDISK to clear the first 512 bytes of the data area
-of a partition whenever a size change occurs. DOS FORMAT will look at
-this extra information even if the /U flag is given -- we consider
-this a bug in DOS FORMAT and DOS FDISK.
-
-The bottom line is that if you use cfdisk or fdisk to change the size of a
-DOS partition table entry, then you must also use
-.B dd
-to zero the first 512 bytes of that partition before using DOS FORMAT to
-format the partition. For example, if you were using cfdisk to make a DOS
-partition table entry for /dev/hda1, then (after exiting fdisk or cfdisk
-and rebooting Linux so that the partition table information is valid) you
-would use the command "dd if=/dev/zero of=/dev/hda1 bs=512 count=1" to zero
-the first 512 bytes of the partition.
-.B BE EXTREMELY CAREFUL
-if you use the
-.B dd
-command, since a small typo can make all of the data on your disk useless.
-
-.B BE EXTREMELY CAREFUL
-if you use the
-.B dd
-command, since a small typo can make all of the data on your disk useless.
-
-For best resutls, you should always use an OS-specific partition table
-program. For example, you should make DOS partitions with the DOS FDISK
-program and Linux partitions with the Linux fdisk or Linux cfdisk program.
-
-.SH COMMANDS
-.B cfdisk
-commands can be entered by pressing the desired key (pressing
-.I Enter
-after the command is not necessary). Here is a list of the available
-commands:
-.TP
-.B b
-Toggle bootable flag of the current partition. This allows you to
-select which primary partition is bootable on the drive.
-.TP
-.B d
-Delete the current partition. This will convert the current partition
-into free space and merge it with any free space immediately
-surrounding the current partition. A partition already marked as free
-space or marked as unusable cannot be deleted.
-.TP
-.B g
-Change the disk geometry (cylinders, heads, or sectors-per-track).
-.B WARNING:
-This option should only be used by people who know what they are
-doing. A command line option is also available to change the disk
-geometry. While at the change disk geometry command line, you can
-choose to change cylinders
-.RB ( c ),
-heads
-.RB ( h ),
-and sectors per track
-.RB ( s ).
-The default value will be printed at the prompt which you can accept
-by simply pressing the
-.I Enter
-key, or you can exit without changes by pressing the
-.I ESC
-key. If you want to change the default value, simply enter the
-desired value and press
-.IR Enter .
-The altered disk parameter values do not take effect until you return
-the main menu (by pressing
-.IR Enter " or " ESC
-at the change disk geometry command line. If you change the geometry
-such that the disk appears larger, the extra sectors are added at the
-end of the disk as free space. If the disk appears smaller, the
-partitions that are beyond the new last sector are deleted and the
-last partition on the drive (or the free space at the end of the
-drive) is made to end at the new last sector.
-.TP
-.B h
-Print the help screen.
-.TP
-.B m
-Maximize disk usage of the current partition. This command will
-recover the the unused space between the partition table and the
-beginning of the partition, but at the cost of making the partition
-incompatible with DOS, OS/2 and possibly other operating systems.
-This option will toggle between maximal disk usage and DOS, OS/2,
-etc. compatible disk usage. The default when creating a partition is
-to create DOS, OS/2, etc. compatible partitions.
-.TP
-.B n
-Create new partition from free space. If the partition type is
-.IR Primary " or " Logical ,
-a partition of that type will be created, but if the partition type is
-.IR Pri/Log ,
-you will be prompted for the type you want to create. Be aware that
-(1) there are only four slots available for primary partitions and (2)
-since there can be only one extended partition, which contains all of
-the logical drives, all of the logical drives must be contiguous (with
-no intervening primary partition).
-.B cfdisk
-next prompts you for the size of the partition you want to create.
-The default size, equal to the entire free space of the current
-partition, is display in megabytes. You can either press the
-.I Enter
-key to accept the default size or enter a different size at the
-prompt.
-.B cfdisk
-accepts size entries in megabytes
-.RB ( M )
-[default], kilobytes
-.RB ( K ),
-cylinders
-.RB ( C )
-and sectors
-.RB ( S )
-by entering the number immediately followed by one of
-.RB ( M ", " K ", " C " or " S ).
-If the partition fills the free space available, the partition is
-created and you are returned to the main command line. Otherwise, the
-partition can be created at the beginning or the end of the free
-space, and
-.B cfdisk
-will ask you to choose where to place the partition. After the
-partition is created,
-.B cfdisk
-automatically adjusts the other partition's partition types if all of
-the primary partitions are used.
-.TP
-.B p
-Print the partition table to the screen or to a file. There are
-several different formats for the partition that you can choose from:
-.sp
-.RS
-.TP
-.B r
-Raw data format (exactly what would be written to disk)
-.TP
-.B s
-Partition table in sector order format
-.TP
-.B t
-Partition table in raw format
-.RE
-
-.RS
-The
-.I raw data format
-will print the sectors that would be written to disk if a
-.BR w rite
-command is selected. First, the primary partition table is printed,
-followed by the partition tables associated with each logical
-partition. The data is printed in hex byte by byte with 16 bytes per
-line.
-
-The
-.I partition table in sector order format
-will print the partition table ordered by sector number. The fields,
-from left to right, are the number of the partition, the partition
-type, the first sector, the last sector, the offset from the first
-sector of the partition to the start of the data, the length of the
-partition, the filesystem type (with the hex value in parenthesis),
-and the flags (with the hex value in parenthesis). In addition to the
-primary and logical partitions, free and unusable space is printed and
-the extended partition is printed before the first logical partition.
-
-If a partition does not start or end on a cylinder boundary or if the
-partition length is not divisible by the cylinder size, an asterisks
-.RB ( * )
-is printed after the non-aligned sector number/count. This usually
-indicates that a partition was created by an operating system that
-either does not align partitions to cylinder boundaries or that used
-different disk geometry information. If you know the disk geometry of
-the other operating system, you could enter the geometry information
-with the change geometry command
-.RB ( g ).
-
-For the first partition on the disk and for all logical partitions, if
-the offset from the beginning of the partition is not equal to the
-number of sectors per track (i.e., the data does not start on the
-first head), a number sign
-.RB ( # )
-is printed after the offset. For the remaining partitions, if the
-offset is not zero, a number sign will be printed after the offset.
-This corresponds to the
-.I NC
-flag in the partitions section of the main display.
-
-The
-.I partition table in raw format
-will print the partition table ordered by partition number. It will
-leave out all free and unusable space. The fields, from left to
-right, are the number of the partition, the flags (in hex), the
-starting head, sector and cylinder, the filesystem ID (in hex), the
-ending head, sector and cylinder, the starting sector in the partition
-and the number of sectors in the partition. The information in this
-table can be directly translated to the
-.IR "raw data format" .
-
-The partition table entries only have 10 bits available to represent
-the starting and ending cylinders. Thus, when the absolute starting
-(ending) sector number is on a cylinder greater than 1023, the maximal
-values for starting (ending) head, sector and cylinder are printed.
-This is the method used by OS/2, and thus fixes the problems
-associated with OS/2's fdisk rewriting the partition table when it is
-not in this format. Since Linux and OS/2 use absolute sector counts,
-the values in the starting and ending head, sector and cylinder are
-not used.
-.RE
-.TP
-.B q
-Quit program. This will exit the program without writing any data to
-disk.
-.TP
-.B t
-Change the filesystem type. By default, new partitions are created as
-.I Linux
-partitions, but since
-.B cfdisk
-can create partitions for other operating systems, change partition
-type allows you to enter the hex value of the filesystem you desire.
-A list of the know filesystem types is displayed. You can type in the
-filesystem type at the prompt or accept the default filesystem type
-.RI [ Linux ].
-.TP
-.B u
-Change units of the partition size display. It will rotate through
-megabytes, sectors and cylinders.
-.TP
-.B W
-Write partition table to disk (must enter an upper case W). Since
-this might destroy data on the disk, you must either confirm or deny
-the write by entering `yes' or `no'. If you enter `yes',
-.B cfdisk
-will write the partition table to disk and the tell the kernel to
-re-read the partition table from the disk. The re-reading of the
-partition table works is most cases, but I have seen it fail. Don't
-panic. It will be correct after you reboot the system. In all cases,
-I still recommend rebooting the system--just to be safe.
-.TP
-.I Up Arrow
-.TP
-.I Down Arrow
-Move cursor to the previous or next partition. If there are more
-partitions than can be displayed on a screen, you can display the next
-(previous) set of partitions by moving down (up) at the last (first)
-partition displayed on the screen.
-.TP
-.I CTRL-L
-Redraws the screen. In case something goes wrong and you cannot read
-anything, you can refresh the screen from the main command line.
-.TP
-.B ?
-Print the help screen.
-
-.RE
-All of the commands can be entered with either upper or lower case
-letters (except for
-.BR W rites).
-When in a sub-menu or at a prompt to enter a filename, you can hit the
-.I ESC
-key to return to the main command line.
-.SH OPTIONS
-.TP
-.B \-a
-Use an arrow cursor instead of reverse video for highlighting the
-current partition.
-.TP
-.B \-v
-Print the version number and copyright.
-.TP
-.B \-z
-Start with zeroed partition table. This option is useful when you
-want to repartition your entire disk.
-.I Note:
-this option does not zero the partition table on the disk; rather, it
-simply starts the program without reading the existing partition
-table.
-.TP
-.BI \-c " cylinders"
-.TP
-.BI \-h " heads"
-.TP
-.BI \-s " sectors-per-track"
-Override the number of cylinders, heads and sectors per track read
-from the BIOS. If your BIOS or adapter does not supply this
-information or if it supplies incorrect information, use these options
-to set the disk geometry values.
-.TP
-.BI \-P " opt"
-Prints the partition table in specified formats.
-.I opt
-can be one or more of "r", "s" or "t". See the
-.BR p rint
-command (above) for more information on the print formats.

-.TH FRAG 8 "8 January 1994" "Linux 0.99" "Linux Programmer's Manual"
-.SH NAME
-frag \- simple fragmentation checker
-.SH SYNOPSIS
-.B /usr/sbin/frag
-.B "[ \-s [ \-s ]]"
-filename ...
-.SH DESCRIPTION
-.B frag
-will report the file system fragmentation on a specified
-.IR filename .
-If the
-.I filename
-is a directory,
-.B frag
-will recursively descend the directory.
-.SH OPTIONS
-.TP
-.B \-s
-Silent (may be set to 1 or 2). The first
-.B \-s
-eliminates the file by file statistics, and just prints the
-examined directories and a summary. The second
-.B \-s
-eliminates the printing of the directories, and just prints a
-summary. This option is useful when
-.B frag
-is used on a directory.
-.SH "SEE ALSO"
-.BR mkfs (8),
-.BR fsck (8),
-.BR mkefs (8),
-.BR efsck (8)
-.SH BUGS
-.B frag
-will get caught in an infinite loop in the /proc filesystem.

.SH NAME
mkswap \- set up a Linux swap area
.SH SYNOPSIS
-.B "mkswap [ \-c ]"
-.IB device " [" size-in-blocks "]"
+.BI "mkswap [\-c] [\-v" N "] [\-f] " device " [" size "]"
.SH DESCRIPTION
.B mkswap
sets up a Linux swap area on a device or in a file.
+(After creating the swap area, you need the
+.B swapon
+command to start using it. Usually swap areas are listed in
+.I /etc/fstab
+so that they can be taken into use at boot time by a
+.B swapon -a
+command in some boot script.)
+
The
.I device
-is usually of the following form:
-
-.nf
-.RS
-/dev/hda[1-8]
-/dev/hdb[1-8]
-/dev/sda[1-8]
-/dev/sdb[1-8]
-.RE
-.fi
+argument will usually be a disk partition (something like
+.I /dev/hda4
+or
+.IR /dev/sdb7 )
+but can also be a file.
+The Linux kernel does not look at partition Id's, but
+many installation scripts will assume that partitions
+of hex type 82 (LINUX_SWAP) are meant to be swap partitions.
The
-.I size-in-blocks
-parameter is the desired size of the file system, in blocks. This
-information is determined automatically by
+.I size
+parameter is superfluous but retained for backwards compatibility.
+(It specifies the desired size of the swap area in 1024-byte blocks.
.B mkswap
-if it is omitted. Block counts are rounded down so that the total
-size is an integer multiple of the machine's page size. Only block
-counts in the range MINCOUNT..MAXCOUNT are allowed. If the block count
-exceeds the MAXCOUNT, it is truncated to that value and a warning
-message is issued.
+will use the entire partition or file if it is omitted.)
-The MINCOUNT and MAXCOUNT values for a swap area are:
+Linux knows about two styles of swap areas, old style and new style.
+The last 10 bytes of the first page of the swap area distinguishes
+them: old style has `SWAP_SPACE', new style has `SWAPSPACE2' as
+signature.
-.RS
-MINCOUNT = 10 * PAGE_SIZE / 1024
-.br
-MAXCOUNT = (PAGE_SIZE - 10) * 8 * PAGE_SIZE / 1024
-.RE
+In the old style, the rest of this first page was a bit map,
+with a 1 bit for each usable page of the swap area.
+Since the first page holds this bit map, the first bit is 0.
+Also, the last 10 bytes hold the signature. So, if the page
+size is S, an old style swap area can describe at most
+8*(S-10)-1 pages used for swapping.
+With S=4096 (as on i386), the useful area is at most 133890048 bytes
+(almost 128 MB if you believe in 1 MB=2^20 bytes), and the rest is wasted.
+On an alpha and sparc64, with S=8192, the useful area is at most
+535560992 bytes (almost 512 MB with the same proviso).
-For example, on a machine with 4kB pages (e.g., x86), we get:
+The old setup wastes most of this bitmap page, because zero bits
+denote bad blocks or blocks past the end of the swap space,
+and a simple integer suffices to indicate the size of the swap space,
+while the bad blocks, if any, can simply be listed. Nobody wants
+to use a swap space with hundreds of bad blocks. (I would not even
+use a swap space with 1 bad block.)
+In the new style swap area this is precisely what is done.
+The maximum useful size of a swap area is now (2^31 - 2*S) bytes,
+roughly 2 GB.
-.RS
-MINCOUNT = 10 * 4096 / 1024 = 40
-.br
-MAXCOUNT = (4096 - 10) * 8 * 4096 / 1024 = 130752
-.RE
+Note that before 2.1.117 the kernel allocated one byte for each page,
+while it now allocates two bytes, so that taking a swap area of 2 GB
+in use might require 2 MB of kernel memory.
-As each block is 1kB large, the swap area in this example could have a
-size that is anywhere in the range from 40kB up to 127.6875MB.
+Presently, Linux allows 8 swap areas. The areas in use can be seen
+in the file
+.I /proc/swaps
+(since 2.1.25).
-If you don't know the page size that your machine uses, you may be
-able to look it up with "cat /proc/cpuinfo".
+.B mkswap
+refuses areas smaller than 10 pages.
-The reason for the limit on MAXCOUNT is that a single page is used to
-hold the swap bitmap at the start of the swap area, where each bit
-represents a single page. The reason for the -10, is that the
-signature is "SWAP-SPACE" -- 10 characters.
+If you don't know the page size that your machine uses, you may be
+able to look it up with "cat /proc/cpuinfo" (or you may not -
+the contents of this file depend on architecture and kernel version).
To setup a swap file, it is necessary to create that file before
running
-.B mkswap .
-A sequence of commands similar to the following is reasonable for this
-purpose:
+.B mkswap ,
+e.g. using a command like
.nf
.RS
-# dd if=/dev/zero of=swapfile bs=1024 count=8192
-# mkswap swapfile 8192
-# sync
-# swapon swapfile
+# dd if=/dev/zero of=swapfile bs=1024 count=65536
.RE
.fi
.SH OPTIONS
.TP
.B \-c
-Check the device for bad blocks before creating the file system. If any
-are found, the count is printed. This option is meant to be used for swap
-partitions
-.BR only ,
-and should
-.B not
-be used for regular files! To make sure that regular files do not contain
-bad blocks, the partition that contains the regular file should have been
-created with
-.BR "mkfs -c" .
+Check the device (if it is a block device) for bad blocks
+before creating the swap area.
+If any are found, the count is printed.
+.TP
+.B \-f
+On SPARC, force creation of the swap area.
+Without this option
+.B mkswap
+will refuse to create a v0 swap on a device with a valid SPARC superblock,
+as that probably means one is going to erase the partition table.
+.TP
+.B \-v0
+Create an old style swap area.
+.TP
+.B \-v1
+Create a new style swap area.
+
+.LP
+If no \-v option is given,
+.B mkswap
+will default to old style if the size of the swap area does not
+exceed the maximum size of an old style swap area, and also if
+the current kernel is older than 2.1.117 (and also if PAGE_SIZE
+is less than 2048).
+The new style header does not touch the first block, so may be
+preferable (also if the swap area is small), in case you have
+a boot loader or disk label there.

.SH NAME
fdisk \- Partition table manipulator for Linux

.sp

.sp
(like a swap partition) at cylinder 0, since that will
destroy the disklabel.
+An IRIX/SGI type disklabel can describe 16 partitions,
+the eleventh of which should be an entire `volume' partition,
+while the ninth should be labeled `volume header'.
+The volume header will also cover the partition table, i.e.,
+it starts at block zero and extends by default over five cylinders.
+The remaining space in the volume header may be used by header
+directory entries. No partitions may overlap with the volume header.
+Also do not change its type and make some file system on it, since
+you will lose the partition table. Use this type of label only when
+working with Linux on IRIX/SGI machines or IRIX/SGI disks under Linux.
+
A DOS type partition table can describe an unlimited number
of partitions. In sector 0 there is room for the description
of 4 partitions (called `primary'). One of these may be an
.BR /dev/ed[a-d] ,
and then exit.
.TP
-.B \-b
-When listing partition tables, also output a `Begin' column,
-as earlier versions of fdisk did by default.
-(Note: the values in this column, when given in cylinder units,
-cannot be larger than 1023. There is nothing wrong if Begin and Start
-differ, at least not as far as Linux is concerned.)
-.TP
.B \-u
When listing partition tables, give sizes in sectors instead
of cylinders.
.BR cfdisk ,
.BR fdisk ,
.BR sfdisk .
+.PP
+The IRIX/SGI type disklabel is currently not supported by the kernel.
+Moreover, IRIX/SGI header directories are not fully supported yet.
+.PP
+The option `dump partition table to file' is missing.

+(This is not the same as saving the old partition table:
+a readable version of the old partition table can be saved
+using the \-d option. However, if you create logical partitions,
+the sectors describing them are located somewhere on disk,
+possibly on sectors that were not part of the partition table
+before. Thus, the information the \-O option saves is not a binary
+version of the output of \-d.)
There are many options.

.SH NAME
chsh \- change your login shell
.SH SYNOPSIS
However, it will issue a warning if the shell is not listed in the
.I /etc/shells
file.
+On the other hand, it can also be configured such that it will
+only accept shells listed in this file, unless you are root.
.SH OPTIONS

-.TH LAST 1 "20 March 1992"
-.SH NAME
-last \(em indicate last logins by user or terminal
-.SH SYNOPSIS
-.ad l
-.B last
-.RB [ \-\fP\fInumber\fP ]
-.RB [ \-f
-.IR filename ]
-.RB [ \-t
-.IR tty ]
-.RB [ \-h
-.IR hostname ]
-.RI [ name ...]
-.ad b
-.SH DESCRIPTION
-\fBLast\fP looks back in the \fBwtmp\fP file which records all logins
-and logouts for information about a user, a teletype or any group of
-users and teletypes. Arguments specify names of users or teletypes of
-interest. If multiple arguments are given, the information which
-applies to any of the arguments is printed. For example ``\fBlast root
-console\fP'' would list all of root's sessions as well as all sessions
-on the console terminal. \fBLast\fP displays the sessions of the
-specified users and teletypes, most recent first, indicating the times
-at which the session began, the duration of the session, and the
-teletype which the session took place on. If the session is still
-continuing or was cut short by a reboot, \fBlast\fP so indicates.
-.LP
-The pseudo-user \fBreboot\fP logs in at reboots of the system.
-.LP
-\fBLast\fP with no arguments displays a record of all logins and
-logouts, in reverse order.
-.LP
-If \fBlast\fP is interrupted, it indicates how far the search has
-progressed in \fBwtmp\fP. If interrupted with a quit signal \fBlast\fP
-indicates how far the search has progressed so far, and the search
-continues.
-.SH OPTIONS
-.IP \fB\-\fP\fInumber\fP
-limit the number of entries displayed to that specified by \fInumber\fP.
-.IP "\fB\-\fP \fIfilename\fP"
-Use \fIfilename\fP as the name of the accounting file instead of
-.BR /etc/wtmp .
-.IP "\fB\-t\fP \fItty\fP"
-List only logins on \fItty\fP.
-.IP "\fB\-h\fP \fIhostname\fP"
-List only logins from \fhostname\fP.

.SH NAME
shutdown \- close down the system
.SH SYNOPSIS
.I /etc/singleboot
.I /etc/nologin
.I /var/log/wtmp
+.I /etc/shutdown.conf
.fi
+.SH CONFIG
+The configuration file \fI/etc/shutdown.conf\fP is used to determine
+the action to take when halting the machine. The currently supported
+file format is extremely primitive. The first line must contain two
+strings separated by whitespace. The first string must be
+\fBHALT_ACTION\fP and the second specifies the action you wish to take
+on halt. The options allowed are:
+.TP
+.B halt
+This will simply halt the system. This is the default behaviour.
+Note also that this is the fallback if another option fails.
+.TP
+.B power_off
+This will use the kernel power shutdown facility. This is usually only
+available on machines with Advanced Power Management (APM).
+.TP
+.I programname
+This specifies a command to run to shut down the power. The first
+character must be a "/". Bear in mind that this command will be run
+with only the root filesystem mounted (and it will be read-only), and
+no daemons running.
.SH "SEE ALSO"
.BR umount (8),
.BR login (1),
and at shorter and shorter intervals as "apocalypse approaches."
Some would construe this as a feature.

+Mkminix-0.1 by W. Black
+
+Description
+-----------
+This directory contains a hacked version of mkfs.minix from util-linux 2.8.
+The hack in question was primarily a bit of #ifndef-ing to make it compile
+successfully under DJGPP. Due to DOS's brain-damaged 8.3 filename limitation,
+the executable has been renamed from mkfs.minix to mkminix.exe.
+[Executable deleted in the util-linux distribution.]
+
+Distribution
+------------
+This distribution should have come with both sources and executable. If
+you're missing either, feel free to visit my site at
+http://www.geocities.com/SiliconValley/Network/5508 to get a fresh one if
+you need it.
+
+This program and its source program in util-linux are protected by the GNU
+General Public License. See the file COPYING for details.
+
+Why
+---
+Exactly why would anyone want to create a Minix filesystem under DOS? The
+answer, as far as I am concerned, is in the interest of creating initial
+ramdisks for Linux. By being able to configure an initrd from DOS (or Win
+'95, etc.), you can make the transition to Linux that much easier (think
+Win '95 autoplay Linux distributions, for example).
+
+Phase II of this project would logically be to be able to populate this initrd
+with files. That is my goal for mkminix-0.2.
+
+Installation
+------------
+At this point, everything is pretty much already installed. Just run MKMINIX
+from the DOS prompt. The source will compile under DJGPP if and only if you
+have a copy of linux/minix_fs.h. I included the one from Linux kernel 2.0.30,
+but these files have a way of changing in annoying ways, so it's probably best
+to use one that matches whatever version of Linux you are going to be running
+concurrently. This is if you have to be ABSOLUTELY sure that everything
+matches... BTW, compile line is as follows for DJGPP:
+
+ gcc -o mkminix.exe mkminix.c
+
+Desperate Plea for Attention
+----------------------------
+If you find this program useful (or silly, or a complete waste of time), please
+drop me a line at wjblack@yahoo.com. Thanks!

.SH NAME
.I device
may look like
.IR knuth.cwi.nl:/dir .
+It is possible to indicate a block special device using its
+volume label or UUID (see the \-L and \-U options below).
The file
.I /etc/fstab
.RE
For more details, see
.BR fstab (5).
+Only the user that mounted a filesystem can unmount it again.
+If any user should be able to unmount, then use
+.B users
+instead of
+.B user
+in the
+.I fstab
+line.
The programs
.B mount
Mount the file system read/write. This is the default. A synonym is
.BR "\-o rw" .
.TP
+.BI \-L " label"
+Mount the partition that has the specified
+.IR label .
+.TP
+.BI \-U " uuid"
+Mount the partition that has the specified
+.IR uuid .
+These two options require the file
+.I /proc/partitions
+(present since Linux 2.1.116) to exist.
+.TP
.BI \-t " vfstype"
The argument following the
.B \-t
is used to indicate the file system type. The file system types which are
currently supported are listed in
.IR linux/fs/filesystems.c :
-.IR minix ", " ext ", " ext2 ", " xiafs ", " hpfs ,
-.IR msdos ", " umsdos ", " vfat ,
-.IR proc ", " nfs ", " iso9660 ", " smbfs ", " ncpfs ,
-.IR affs ", " ufs ", " romfs ,

+.IR romfs ,
+.IR ufs ,
.IR sysv ", " xenix ", " coherent .
Note that the last three are equivalent and that
.I xenix
.I xiafs
do not exist anymore.
+For most types all the
+.B mount
+program has to do is issue a simple
+.IR mount (2)
+system call, and no detailed knowledge of the filesystem type is required.
+For a few types however (like nfs, smbfs, ncpfs) ad hoc code is
+necessary. The nfs ad hoc code is built in, but smbfs and ncpfs
+have a separate mount program. In order to make it possible to
+treat all types in a uniform way, mount will execute the program
+.I /sbin/mount.TYPE
+(if that exists) when called with type smb or ncp.
+Since various versions of the
+.I smbmount
+program have different calling conventions,
+.I /sbin/mount.smb
+may have to be a shell script that sets up the desired call.
+
The type
.I iso9660
is the default. If no
type is specified, the superblock is probed for the filesystem type
.RI ( minix ", " ext ", " ext2 ", " xiafs ", " iso9660 ", " romfs
are supported).
-If this probe fails and
-.I /proc/filesystems
-exists, then all of the filesystems listed there will be tried,
+If this probe fails, mount will try to read the file
+.IR /etc/filesystems ,
+or, if that does not exist,
+.IR /proc/filesystems .
+All of the filesystem types listed there will be tried,
except for those that are labeled "nodev" (e.g.,
.I proc
and
Note that the
.B auto
type may be useful for user-mounted floppies.
+Creating a file
+.I /etc/filesystems
+can be useful to change the probe order (e.g., to try vfat before msdos)
+or if you use a kernel module autoloader.
Warning: the probing uses a heuristic (the presence of appropriate `magic'),
and could recognize the wrong filesystem type.

-command appeared in Version 6 AT&T UNIX.
+command existed in Version 5 AT&T UNIX.
* A mount(8) for Linux 0.99.
* mount.c,v 1.1.1.1 1993/11/18 08:40:51 jrs Exp
*
- * Thu Jul 14 07:32:40 1994: faith@cs.unc.edu added changes from Adam
- * J. Richter (adam@adam.yggdrasil.com) so that /proc/filesystems is used
- * if no -t option is given. I modified his patches so that, if
- * /proc/filesystems is not available, the behavior of mount is the same as
- * it was previously.
- *
* Wed Sep 14 22:43:00 1994: Mitchum DSouza
* (mitch@mrc-applied-psychology.cambridge.ac.uk) added support for mounting
* the "loop" device.
* Wed Sep 14 22:55:10 1994: Sander van Malssen (svm@kozmix.hacktic.nl)
* added support for remounting readonly file systems readonly.
*
- * Wed Feb 8 09:23:18 1995: Mike Grupenhoff <kashmir@umiacs.UMD.EDU> added
- * a probe of the superblock for the type before /proc/filesystems is
- * checked.
- *
* Wed Feb 8 12:27:00 1995: Andries.Brouwer@cwi.nl fixed up error messages.
* Sat Jun 3 20:44:38 1995: Patches from Andries.Brouwer@cwi.nl applied.
* Tue Sep 26 22:38:20 1995: aeb@cwi.nl, many changes
* Fri Feb 23 13:47:00 1996: aeb@cwi.nl, loop device related changes
*
- * Fri Apr 5 01:13:33 1996: quinlan@bucknell.edu, fixed up iso9660 autodetect
- *
* Since then, many changes - aeb.
*
* Wed Oct 1 23:55:28 1997: Dick Streefland <dick_streefland@tasking.com>
* Implemented the "bg", "fg" and "retry" mount options for NFS.
+ *
+ * Tue Aug 4 15:54:31 1998: aeb@cwi.nl:
+ * Open fd 0,1,2 so that printf's do not clobber /etc/mtab or so.
+ * Mangle filenames with embedded spaces. Add ufsmagic. Add locking.
+ * Avoid unnecessary error messages about /proc.
+ * Improve support for noncanonical names in /etc/fstab.
+ * Add support for volume labels and UUIDs.

+.PP
+A Linux kernel maintains a concept of a local timezone for the system.
+But don't be misled -- almost nobody cares what timezone the kernel
+thinks it is in. Instead, programs that care about the timezone
+(perhaps because they want to display a local time for you) almost
+always use a more traditional method of determining the timezone: They
+use the TZ environment variable and/or the /usr/local/timezone
+directory, as explained in the man page for tzset(3). However, some
+programs and fringe parts of the Linux kernel such as filesystems use
+the kernel timezone value. An example is the vfat filesystem. If the
+kernel timezone value is wrong, the vfat filesystem will report and
+set the wrong timestamps on files.
+.PP
+.I hwclock
+sets the kernel timezone to the value indicated by TZ and/or
+/usr/local/timezone when you set the System Time using the
+.B \-\-hctosys
+option.
+.PP
+A complication is that the timezone value actually consists of two
+parts: 1) how far from the Standard Meridian the locality is
+geographically, and 2) whether or not a Daylight Savings Time (DST)
+convention is in effect in the locality at the present time. In
+practice, the DST part of the timezone value is almost never used, so
+if the geographical part were to be set to its correct value, the
+users of the timezone value would actually compute the wrong local
+time.
+.PP
+Therefore,
+.I
+hwclock
+violates the definition of the kernel's timezone value and always sets
+the DST part to zero. If DST is supposed to be in effect,
+.I
+hwclock
+simply adds an hour to the geographical part.

+like ntp to keep your System Time synchronized. (ntp is a way to keep
+your System Time synchronized either to a time server somewhere on the
+network or to a radio clock hooked up to your system. See RFC 1305).
+
+This mode (we'll call it "11 minute mode") is off until something
+turns it on. The ntp daemon xntpd is one thing that turns it on. You
+can turn it off by running anything, including
+.I hwclock --hctosys
+, that sets the System Time the old fashioned way.
+
+To see if it is on or
+off, use the command
+.I adjtimex --print
+and look at the value of "status". If the "64" bit of this number
+(expressed in binary) equal to 0, 11 minute mode is on. Otherwise, it
+is off.
+
+If your system runs with 11 minute mode on, don't use
+.I hwclock --adjust
+or
+.I hwclock --hctosys .
+You'll just make a mess. It is acceptable to use a
+.I hwclock --hctosys
+at startup time to get a reasonable System Time until your system is
+able to set the System Time from the external source and start 11
+minute mode.

-.SH NAME
-lpcntl \- interface to line printer ioctl
-.SH SYNOPSIS
-.BI "lpcntl " device " [ " irq " ]"
-.SH DESCRIPTION
-.B lpcntl
-is used to manipulate the line printer driver.
-.PP
-.I device
-specifies a line printer device (e.g.,
-.IR /dev/lp1 ).
-.PP
-If
-.I irq
-is specified, then the line printer driver is set to use that IRQ. If the
-.I irq
-is zero, then the polling driver is selected. Only the super user may
-change the IRQ.
-.PP
-If no
-.I irq
-is specified, then
-.B lpcntl
-will report the interrupt number currently in use, or will report that the
-polling driver is currently being used.

- WARNING: THIS COLLECTION DOES *NOT* SUPPORT SHADOW PASSWORDS.
-
- WARNING: THIS COLLECTION DOES *NOT* SUPPORT SYSTEM V INITTAB.
-
- WARNING: USE GNU TAR -- OTHER TARS WILL FAIL SILENTLY!

-
- WARNING: *READ* the util-linux-2.1.bin.Notes file *BEFORE* and *AFTER*
- installation: there are a few links you must make by hand.
-
- This is a collection of many assorted utilities for Linux. Some are
- system utilities that are not easily available anywhere elsewhere
- (e.g., mkfs.minix, mkswap); others are BSD ports of common utilities
- that are not yet contained in any FSF package (e.g., col); others are
- non-System-V alternatives to common utilities (e.g., simpleinit,
- agetty, login, passwd).
-
- The arrangement, as nearly as I can determine, conforms to the Linux
- Filesystem Structure, Interim Release 1.1, October 9, 1994, with *NO*
- exceptions. A copy of the standards document can be found at
- tsx-11.mit.edu:/pub/linux/docs/linux-standards/fsstnd/*.
-
- Many people provided patches and suggestions. I deeply appreciate
- this.
-
-
-HIGHLIGHTS for version 2.1:
-
-1) Directory structure rearrange, with configuration support for those who
- use shadow passwords and System V init (no support is provided for these
- things, but your utilities won't get overwritten if you do a "make
- install" after you properly edit MCONFIG).
-2) fdisk and cfdisk should work as expected with 2GB+ disk drives
-3) As usual, lots of stuff was updated and added, including mount, vipw,
- readprofile
-4) Some stuff was also deleted, and can now be found elsewhere:

-
-WARNING: THE PROGRAMS IN THIS SUITE DO *NOT* SUPPORT SHADOW PASSWORD FILES!
-
-WARNING: THIS COLLECTION DOES *NOT* SUPPORT SYSTEM V INITTAB.
-
-WARNING: USE GNU TAR -- OTHER TARS WILL FAIL SILENTLY!
-
-WARNING: DO *NOT* INSTALL WITHOUT THINKING.
-
-WARNING: Read the util-linux-2.1.bin.Notes file *BEFORE* and *AFTER*
- installation: there are a few links you must make by hand.
-
-WARNING: The agetty, simpleinit, login, passwd, and other programs in this
- package are *NOT* System V compliant. These utilities are meant
- to be used by people who build their own systems. If you are not
- a wizard, do *NOT* blindly install these utilities: they could
- prevent you from logging into your system. Have a boot floppy
- ready, especially if you don't know what you are doing.
-
-WARNING: The binary distribution was tarred using GNU TAR AND THE -S OPTION!
- This means that holes will be preserved, but that ONLY GNU TAR
- WILL WORK ON THE BINARY DISTRIBUTION (in fact, other, inferior,
- tar programs will fail silently). YOU HAVE BEEN WARNED!
-
-WARNING: localtime and posixtime default to US/Eastern -- change these now.
-
-
-
-To install from the binary distribution:
-
-1) Get binary distribution (see the .lsm file for locations)
-2) cd /
-3) gtar zpxvf util-linux-2.1.bin.tar.gz
- (or: pms -i util-linux-2.1.bin.tar.gz)
-4) *IF* you want to use agetty and simpleinit, then make softlinks from
- /sbin/init to simpleinit and from /sbin/getty to agetty, but make sure
- that your /etc/inittab is set up right (this is *NOT* the System V
- compatible init!), or you will be hosed.
-5) Run zic -l and/or zic -p to set your timezone. The distribution is set
- up to use /usr/lib/zoneinfo/US/Eastern as the default. This was
- installed with "zic -l US/Eastern"
-6) Remove all the old binaries from previous locations.
-
-
-
-To install from source:
-
-1) Get source distribution (see the .lsm file for locations)
-2) Untar util-linux-2.1.tar.gz in /usr/src
-3) cd util-linux-2.1
-4) Edit MCONFIG:
-
- If you use the shadow password suite and do _not_ want to install
- programs like login and passwd that do not support shadow passwords,
- then set HAVE_SHADOW to yes
-
- If you use the System V init suite and do _not_ want to install programs
- like agetty, simpleinit, and shutdown, then set HAVE_SYSVINIT to yes
-
- If you don't like the compile-time options or the directories, then
- change them. Note that you also can say something like "make OPT=-g
- LDFLAGS=" in order to make a complete debugging version without editing
- the MCONFIG at all.
-
-5) make
-6) make install
-7) If you want to use simpleinit and agetty, then make softlinks from
- /sbin/init to simpleinit and from /sbin/getty to agetty, but make sure
- that your /etc/inittab is set up right (this is *NOT* the System V
- compatible init!), or you will be hosed. If you are using the SysV
- init and/or some other getty, they you can keep using those.
-8) Run zic -l and/or zic -p to set your timezone. The distribution is set
- up to use /usr/lib/zoneinfo/US/Eastern as the default. This was
- installed with "zic -l US/Eastern"
-9) Remove all the old binaries from previous locations.
-
-
-
-HIGHLIGHTS for version 2.1:
-
-1) Directory structure rearrange, with configuration support for those who
- use shadow passwords and System V init (no support is provided for these
- things, but your utilities won't get overwritten if you do a "make
- install" after you properly edit MCONFIG).
-2) fdisk and cfdisk should work as expected with 2GB+ disk drives
-3) As usual, lots of stuff was updated and added, including mount, vipw,
- readprofile
-4) Some stuff was also deleted, and can now be found elsewhere:

-mount:
- mount, umount, swapon
-
- Rick Sladkey put together the mount-0.99.6.tar.Z package, and Stephen
- Tweedie provided updates. The utilities were originally from that
- package (all appear to be by Doug Quale (quale@saavik.cs.wisc.edu),
- with modifications by H. J. Lu (hlu@eecs.wsu.edu) on 11/25/92; Rick
- Sladkey (jrs@world.std.com) in January 1993; and Stephen Tweedie
- <sct@dcs.ed.ac.uk> on 8 October 1993. This distribution mount now
- supports NFS stuff. I have modified the man pages. I have also added
- a small patch from Hamish Glen Coleman (t933093@minyos.xx.rmit.OZ.AU)
- which restores the -o semantics.
-
- Updated with Rick Sladkey's mount-0.99.14.tar.gz package, and with
- extra patches from Rick. Adam J. Richter allowed -t option to be
- optional. Patrick J. Volkerding (volkerdi@mhd1.moorhead.msus.edu) and
- Mitchum DSouza both provided patches that fixed the (null) problem when
- not using -t. Mitchum DSouza
- (mitch@mrc-applied-psychology.cambridge.ac.uk) added support for loop
- device mounts. Sebastian Lederer
- (lederer@next-pc.informatik.uni-bonn.de) added support for sending an
- unmount RPC call to the server when an NFS-filesystem is unmounted.
- Sander van Malssen (svm@kozmix.hacktic.nl) added support for remounting
- readonly file systems readonly. Mike Grupenhoff
- <kashmir@umiacs.UMD.EDU> added a probe of the superblock for the type
- before /proc/filesystems is checked. Andries.Brouwer@cwi.nl fixed up
- error reporting.
-
-selection:
- The complete selection-1.5 package, by Andrew Haylett
- <ajh@gec-mrc.co.uk>, 17th June 1993, is included. Kernel patches are
- no longer necessary for modern kernels, but these were tiny so I left
- them in for historical reasons. The Makefile was modified for this
- distribution. With changes from Rick Sladkey.
