mount: mtab created multiple times with -a option
When /etc/mtab does not exist and mount is called with -a, for every
mount point that is mounted a root-fs record is added to mtab. This is
because get_mtab_info() sets the flag mtab_does_not_exist to 1 when it
doesn't find /etc/mtab. However, if it actually finds /etc/mtab, the
variable is not reset to 0. So on every subsequent call to
get_mtab_info() (as it is the case when mounting several mount points
with the -a option), mount will think that /etc/mtab does not exist,
even if it was created in the meantime by mount itself.

Linux cannot umount a device whose mount point is hidden by subsequent
mount(s). i.e. We must umount the devices associated to a mount point
in the reverse order of when they were mounted. If umount was called
violating this rule, report error and exit.

losetup: remove dependence on minor numbers
The latest kernel supports partitioned loop devices (kernel commit 476a4813cfddf7cf159956cc0e2d3c830c1507e3). Unfortunately, this change

It makes no sense to allow translators to adjust the spacing when
they cannot adjust the spacing of the actual data too. Adjusting

3. New prompt. Wait several seconds, then type "true" and hit return.
4. Repeat (3) as desired, then exit scripted shell.
5. Run "scriptreplay timing".
You'll find on the replay that, rather than waiting several seconds

losetup: looplist_* refactoring, remove scandir()
This patch replaces scandir-based implementation with readdir(). The
readdir(3) is less expensive and more portable (to non-glibc environment).
The patch also replaces sysfs-based solution with simpler /proc/partitions
parsing. The /proc/partitions includes all used loop devices on all systems
(include 2.4). This solution seems faster than scandir(/sys/block/) too.
Summary, the losetup (with this patch) uses three methods to found a
loop device:
a) parse /proc/partitions to found already used loop devices (for
loserup -a)
b) stat(2) for all loop[0-7] devices (default number of loop devices).
This is classic method from util-linux <= 2.13. This method is good
enough for standard Linux machines with default number of loop
devices.
c) scan all /dev or /dev/loop/ for loop devices. This is useful for
crazy people who need more than 8 loop devices.

mount: retry on ENOMEDIUM
Due to a change in kernel behaviour when opening CDROM devices,
we need to retry the open/mount call when ENOMEDIUM is returned.
Explanation from Tejun Heo:
Okay, the difference is from the addition of cdrom_get_media_event()
call to both sr_drive_status() and ide_cdrom_drive_status().
Previously, the cdrom driver can't differentiate between tray closed
w/ no media and tray open and always returned tray open, which
triggers close and retry in the open logic which probably have delayed
things enough to get the media recognized.
Now the cdrom driver can discern between tray closed w/o media and
device not ready for other reasons and returns -ENOMEDIUM on the
former. This is all good and dandy but the problem seems that some
drives report no media right after the tray is closed but it hasn't
properly detected the media yet.
It seems the only way to work around the problem is via sensible
retries (e.g. try three times 5 secs apart) and I don't think we can
add that type of retry logic into cdrom open path. Please note that
the previous logic wasn't water proof. Some drives can take longer to
recognize the media is there and could have failed the in-kernel retry
too. Also, reading the media can take quite some time and during that
period the drive reports media present but device not ready. The
driver will retry the command (e.g. READ TOC for open) five times but
all of them can fail w/ EMEDIUMTYPE.
