Public bug reported:
I have the following entry in /etc/fstab:
UUID=00a1665a-f7f1-48c6-8dff-65e77c98bd2f /media/extdisk ext3
user,noauto,exec 0 0
- to allow a nonprivileged user (ie, me) to mount a firewire disk with
the specified UUID.
mounting works fine, but unmounting (as the same user) doesn't:
[EMAIL PROTECTED] ~]$ umount /media/extdisk
umount: /media/extdisk mount disagrees with the fstab
When this disk is mounted, /proc/mounts shows:
/dev/disk/by-uuid/00a1665a-f7f1-48c6-8dff-65e77c98bd2f /media/extdisk ext3
rw,nosuid,nodev,data=ordered 0 0
however, /etc/mtab shows:
/dev/sda1 /media/extdisk ext3 rw,nosuid,nodev,user=jk 0 0
If I strace the umount:
[EMAIL PROTECTED] ~]$ sudo strace -etrace=file -u jk umount /media/extdisk/
execve("/bin/umount", ["umount", "/media/extdisk/"], [/* 31 vars */]) = 0

umount: /media/extdisk mount disagrees with the fstab
Process 10417 detached
- umount has managed to resolve the symlink from /dev/disk/by-uuid/00...
to /dev/sda1, but hasn't recognised that it's the same device ?
