When creating the "/etc/mtab~" lockfile (specifically 'linktargetfile' in the
lock_mtab function), the file is created with incorrect permissions ('000')
which necessitates root to leverage CAP_DAC_OVERRIDE. If proper file modes (it
would appear 0600 would be sufficient) were used in the open this would
function properly with CAP_DAC_OVERRIDE revoked.
$ sysctl -w kernel.cap-bound=0xf7fd7df5
$ mount -t tmpfs /dev/swap /mnt
can't open lock file /etc/mtab~: Permission denied (use -n flag to override)

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.
Output for idle class will not contain prio data.
Fix inconsistency between kernel profiling and readprofile.
The range of kernel profiling is between _stext and _etext,
and readprofile tries to extract profiling for all the symbols in
/boot/System.map-2.6.16.11-7-ppc64 from /proc/profile, but there
are more symbols in /boot/System.map-2.6.16.11-7-ppc64 than those
between _stext and _etext.

build-sys: missing header when NLS is disabled
Compiling utils fail when disable NLS with the --disable-nls switch.
"mkfs.c:46: error: 'LC_ALL' undeclared (first use in this function)"
It is due to a missing locale.h header : When enabling NLS, nls.h
includes libintl.h, which in turn includes locale.h. When disabling NLS,
libintl.h isn't anymore included nor locale.h, which is needed for the
setlocale() calls.

tests: use relative paths when sourcing files
The "." command will search $PATH before $PWD if the argument
specified contains no path qualifiers which can cause problems if
you happen to have something in $PATH named the same. The
attached patch changes all of the ". <foo>" in the tests subdir.
git is neat. It feels like tla, only with a usable interface,
less bugs and decent performance.
I'm not sure if I got all the git workflow correct, however first
patch attached. It's been tested and is clean and useful. (221290)
Can git commits be split afterwards? If I add a diff to debian/changelog
for closing a bug, does that interfere with pushing the code change
to the upstream, who doesn't care about debian/changelog?
Cheers,
Moritz

fdisk: check returns in fdisk from partition changes
currently the code in fdisk which changes partition types is a bit fragile ...
it assumes the partition type succeeded instead of checking the user input or
for errors. ive tweaked the sub functions to return a value indicative of the
functions' success and fdisk now checks/reports based on that.

sys-utils: add arch(1) back to the official tree
This patch add arch(1) back to util-linux source code tree, but the
command is not installed by defautl.
For more details see "./configure --help".
The arch command is deprecated in favor of "uname -m" (coreutils). The
latest (6.9+) version of coreutils also supports arch(1) as an alias
to "uname -a". Please, if you need arch(1) use the coreutils
implementation.

lomount.c: don't use mlockall if CRYPT_NONE
loop back mounting emits two system calls: mount and mlockall.
mount is obviously needed. mlockall is needed for encryption.
As the result both CAP_SYS_ADMIN and CAP_IPC_LOCK are needed
to do loopback mounting.
The problem is that CAP_IPC_LOCK is always needed through my
command doesn't need encryption.
With the following patch, mount calls mlockall only when
encryption is needed.
