* mount: mention mtab for single mount point mount in mount.8Peter Volkov2009-08-181-1/+3
| | | | | | | | | | | | | | Karel Zak wrote: "This is very old (10+years) feature. The mount(8) is trying to found mountpoint/device in fstab and then in mtab. I guess the original purpose for this feature is user-friendly 'mount /node -o remount'. Unfortunately, the code does not check for MS_REMOUNT flag and consults mtab in all cases. (The code is consulting fstab/mtab before mount options parsing.)" This commit documents this feature. Signed-off-by: Karel Zak <kzak@redhat.com>

| | | | | | | | | This reverts commit 98c7944b52c54c86fb5b9d73fbead9442bfa0e30. Unfortunately, the patch has been committed by "git commit -a" and includes unwanted changes in configure.ac and sys-utils/Makefile.am... Sorry.

* mount: when a remount to rw fails, quit and return an errorValerie Aurora2009-07-141-0/+4
| | | | | | | | | | | | | | | A nice feature of mount is that when you attempt to mount a file system read-write, and that fails because it can only be mounted read-only, it goes ahead and retries the mount with the "ro" option and returns success if that succeeds. However, this code path is also followed when you are doing a remount for the sole purpose of changing the mount from read-only to read-write - the change fails, but mount returns success. Instead, check if we are attempting to remount and fail out immediately, instead of retrying with the old "ro" option and whee, happily "succeeding."

* losetup: handle symlinks in /dev/loop/Mike Frysinger2009-05-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The loop_scandir() expects all the files in /dev/loop/ to be actual devices and not symlinks to devices. However, udev by default sets up symlinks in /dev/loop/ thereby breaking the fallback scan logic when looking for devices more than the default number of 8. Simple way to reproduce is: - <detach all devices> - cd /dev/loop - rm -f [2-7] - losetup 0 autogen.sh - mv 1 8 - for n in {1..7} ; do ln -s 0 $n ; done - losetup -f <error but should have found /dev/loop/8> [kay.sievers@vrfy.org: just a note, udev does not do that by default. It is devfs-nonsense, which the "default" never did.] Signed-off-by: Mike Frysinger <vapier@gentoo.org> Reported-by: Mario Bachmann <grafgrimm77@gmx.de>
