The example in the man page does not prevent concurrent execution, as it
obtains a shared lock. More useful is taking an exclusive lock, i.e.
remove "-s".
Additionally, IMO most people want the script to exit when the lock
cannot be acquired, so adding "-n".
If linux/falloc.h does not exist, the build system still enables the
fallocate util, but ultimately fails when it tries to include the
header and use a define from it.

Older versions of glibc used to declare ‘union semun’ in <sys/sem.h>,
but POSIX.1-2001 requires the caller to declare it instead. Later
versions of glibc started defining _SEM_SEMUN_UNDEFINED to note that
the union was not being declared, but conforming systems are not
required to define that macro (e.g. FreeBSD). As a side effect we get
rid of some obsolete __GNU_LIBRARY__ macro usage.

The fallocate(1) utility is used to preallocate blocks to a file.
This can be useful for virtual images, database files, testing, etc.
Normally we'd hope that various tools will start using preallocation
internally, but until then such a utility may be useful, and could be
scripted as well.
The original Eric's version is available at:
http://thread.gmane.org/gmane.linux.utilities.util-linux-ng/2490
This version:
- checks for fallocate glibc function and kernel syscall
- does not provide a fallback and does not call posix_fallocate()
- adds long options
- uses err.h for errro messages
- adds NLS support
- cleanups man page

The current switch_root can only switch to a new root that is the root
of a mount point.
This patch adds support for "subroots", where the new root is
somewhere below a mount point. It does this by adding in a few extra
steps to chroot into the subroot after the enclosing partition has
been moved and entered.
This will be used by OLPC, who sort-of have 2 copies of Fedora stored
on a single partition under different directory trees, where the
initramfs decides which one to boot into

Cleanups for rtcwake:
- Minor doc updates: highlight the framebuffer problem,
give correct history of this code
- Improve debug output
- Fix some linelength bugs
Note that this code predated the sysfs "wakealarm" mechanism, and
works around several now-fixed bugs in the kernel RTC framework.
Nowadays it would make sense to make this program use only the sysfs
interface to the RTC, using "since_epoch" instead of RTC_RD_TIME and
"wakealarm" instead of the four other ioctls. That could simplify
the mess involved in timezone handling.
