Package: lvm10
Version: 1:1.0.8-8.cj
Severity: normal
Hello.
If one symlinks /proc/mounts to /etc/mtab, lvmcreate_initrd doesn't
work:
# lvmcreate_initrd
...
lvmcreate_initrd -- creating new /etc/fstab
lvmcreate_initrd -- ummounting ram disk
umount: /tmp/initrd.3115: not mounted
lvmcreate_initrd -- ERROR umounting /tmp/initrd.3115
rmdir: »/tmp/mnt.3115«: Das Gerät oder die Ressource ist belegt
This is because umount references the *source* of the mount, but since
this is a loop mount, the kernel only keeps "/dev/loop0" or similar as
source of the mount in /proc/mounts, thus umount fails.
Replacing the source with the target solves the problem. See below
patch. This should also work with /etc/mtab being a file as "usual"
(not a symlink) (untested).
Thanks for applying.
Cheers,
Christian.
