These options allow to specify alternative groups. The command
su(1) has to be executed by root. The implementation is based on
Fedora runuser(1) command.
For example:
# su --group=kzak --supp-group=uuidd -
# id
uid=0(root) gid=1000(kzak) groups=0(root),985(uuidd),1000(kzak)
non-root user:
$ su --group=kzak -
su: only root can specify alternative groups

This matches more closely with what 'df -h' reports as space available.
Any remaining discrepancy between these 2 tools is a result of precision
and choices in rounding.

# mount -n -o ro /dev/sda1 /
# mount -o remount,rw /dev/sda1 /
For the backward compatibility the command mount(8) should to add a
new entry to the file /etc/mtab on remount if the original entry not
found (because previous mount has been called with -n).

We should not care about mountpoints in fsck if a device name
specified on command line, just check if the device is used somewhere
in /proc/self/mountinfo file.
Crazy people who use
fsck /mountpoint
have to specify the mountpoint by the same format as in their fstab --
symlinks canonicalization is not supported.

The old implementation always canonicalizes target (mountpoint) path.
It's better to postpone this operation until the path is really
necessary (usually it's unnecessary), because readlink() on mountpoint
may trigger automounts.

autoconf docs about *dir variables (e.g bindir):
... A corollary is that you should not use these variables except in
makefiles...
...you should not rely on AC_CONFIG_FILES to replace bindir and friends
in your shell scripts and other files; instead, let make manage their
replacement.

The --separator and --columns long options in util-linux-2.21.2 and in
a git clone from 5 minutes ago, don't work:
$ echo foobar | column -s x
foobar
$ echo foobar | column -c 10
foobar
$ echo foobar | column --separator=x
column: option '--separator' doesn't allow an argument
$ echo foobar | column --separator x
Segmentation fault
$ echo foobar | column --columns 10
column: bad columns width value: '(null)': Invalid argument
$ echo foobar | column --columns=10
column: option '--columns' doesn't allow an argument
Looks like a simple case of missing has_arg flag in the "struct
option" initialization for these two options. The patch just adds the
flag. I haven't done thorough testing of the patched code, but it
seems to work OK and it no longer segfaults or tries to dereference a
null pointer.

For init_kmsg, it cause switch to DMESG_METHOD_SYSLOG

loopdev.c, test_pager, and get_max_number_of_cpus() are linux-specific.
get_linux_version will only work on Linux, let's introduce
system_supports_ext4_ext2() which assumes that mounting ext2 with ext4
is not supported on non-Linux systems.
