Followup-For: Bug #396215
I can confirm this problem in the current version of gnome-vfs from
unstable (2.22.0-5). A filesystem will be displayed twice (once
mounted, once unmounted) in Nautilus, the GNOME file dialog, etc. if:
1. the FS is currently mounted;
2. it is listed in /etc/fstab;
3. it has the 'user' option in fstab; AND
4. the fstab record's fs_spec uses LABEL=, refers to a symlink
(such as /dev/disk/by-id/foo), or otherwise differs from the
device listed in /proc/mounts.
(it might also be necessary for the user option to be listed in
/proc/mtab; I haven't tested the case where it is in fstab but
not mtab)
Two pairs of entries on my system which cause duplicates:
/etc/fstab:
LABEL=backup_ext /media/backup_ext ext3
user,noauto,noexec,nosuid,acl,user_xattr 0 0
/dev/disk/by-label/IPOD /media/ipod vfat
user,noauto,noexec,fmask=177,dmask=077 0 0
/proc/mounts:
/dev/sdb1 /media/backup_ext ext3
rw,nosuid,nodev,noexec,errors=continue,user_xattr,acl,data=ordered 0 0
/dev/sdg2 /media/ipod vfat
rw,nosuid,nodev,noexec,fmask=0177,dmask=0077,codepage=cp437,iocharset=utf8 0 0
The Debian gnome-vfs package already contains a patch
(15_uuid_mount.patch) that fixes the problem for UUID= mounts by
making the following changes:
1. Chase symlinks that appear in fsnames in /proc/mounts (/etc/mtab).
2. If the fsname in fstab is "UUID=foo", replace that with
/dev/disk/by-uuid/foo and chase symlinks.
3. If this is not a symlink, or if realpath fails, skip this
mountpoint entirely
The attached patch, to be applied AFTER 15_uuid_mount.patch, extends
the logic for fstab further:
4. If the fsname in fstab is "LABEL=foo", replace that with
/dev/disk/by-label/foo (and skip the mountpoint if that
is not a link).
5. Always chase symlinks that appear in fstab. This allows
/dev/disk/by-id/foo and other symlinks to work.
thus fixing the duplicate mountpoint problem for LABEL= and symlink
mountpoints.
This patch applies cleanly to the gnome-vfs from experimental
(2.24.0-1), but I have not tested with that version.
