chsh: don't use empty shell field in /etc/passwd
chsh(1) uses empty shell setting (pw->pw_shell="") as a synonym for
/bin/sh. This convention is silly and unnecessary. (The vsftpd server
will not run if the shell assigned to user "ftp" is a null string --
according to bug rh#103004).

mount: fix incorrect behavior when more than one fs type is specified
"mount" may fail when more than one file system type is specified, and the
requested access mode is read/write, but the device is read-only. The error
message is: "mount: wrong fs type, bad option, bad superblock on...".
It works only if the correct file system type is the last item in the comma
separated list. This is because when it tries to mount the file system again
in read-only mode, the "types" parameter passed to the "try_mount_one"
function contains only the last item instead of the entire list.
For example, you cannot mount a UDF CD/DVD with "-t udf,iso9660" if you
don't also add the read-only option. This means that some Linux distributions
with the default configuration may not be able to mount UDF disks
automatically (e.g. Ubuntu Dapper - Gutsy Tribe 3).

script: fix race conditions
script(1) uses three processes (doinput, dooutput and doshell). It's
possible that the shell process is finished before the input and
output processes are completely initialized. For example:
$ script -c "printf Bingo"
In particular case the output and input processes read/write data from
shell process in time when the shell process is already done -- so it
hangs on read().
The second problem is that the output process can finish although
there are unread data from finished shell process -- an output in
the typescript file and on terminal is incomplete!
script(1) has to pass:
$ for i in `seq 1 1000`; do script -q -c "printf 'Bingo\n'"; done | grep -c Bingo

agetty: 8 bit characters on the Linux console lead to input corruption
8 bit characters on the Linux console lead to input corruption (e.g.
German umlauts). This is easily reproducable by inserting a login name with
umlaut and typing backspace afterwards.
agetty supports tty parity, which leads to getty treating these characters
as a 7bit char with set parity.
This patch by Samuel Thibault adds a new option -8 which disables parity
detection for ttys not used for serial logins.
| Note: With this patch, 8bit characters are just silently dropped (that's
| the expected getty behavior), this is quite neat since you then don't
| even need to backspace your 8bit characters :)
The idle class has no class data. It will print a warning if
a prio argument is given for it, since this will be ignored.

fdisk: many significant improvements and fixes to Sun label handling
1) Properly describe the exact layout and fields of the sun disk
label. Several fields were incorrectly mentioned and others
wrongly sized.
2) Properly set the version, sane, and num_partitions fields.
Because we weren't doing this, programs such as Solaris's format
and the Solaris kernel itself refused to recognize our disk labels
as valid.
3) Move SSWAP*() macros into fdisksunlabel.c as there is no reason
for them to be exposed to the rest of fdisk.
4) Kill the sun_predefined_drives array hack and assosciated code.
Instead size the disk and figure out the geometry properly just
like the SGI and MSDOS partition handling do, by means of the
HD_GETGEO ioctl() and disksize().
5) If the disk label read is found to not have the proper values
set in version, sane, or num_partitions, fix them, recompute the
label checksum, dirty the disk label, and let the user know what
we did and that the fixed values will be written out if they 'w'.
This gives users an easy way to fix up disk labels created by
disk labelling programs which had this bug.
6) Create a sun_sys_getid() function so that fdisk.c does not need
to reference the sun disk label details directly, just like the
SGI code does.

In Linux 2.6 the BLKRASET ioctl has the desired effect for mounted

read-ahead on the *device* as opposed to within a *file*, and the
maximum value of this number is 255. As a result the invocation of
blockdev will fail on Linux 2.4 for any usefully large value of
READAHEAD, and will not in any case have the desired affect for
fragmented files.
