Package: duplicity
Version: 0.6.18-2
Severity: normal
My firefox profile directory is a symlink to an encfs mount point:
[23+0]~$ ls -l .mozilla/firefox/
total 8
drwxr-xr-x 5 itz itz 4096 Jul 21 23:00 failsafe
lrwxrwxrwx 1 itz itz 29 Feb 18 2012 firefox-profile ->
../../Private/firefox-profile
-rw-r--r-- 1 itz itz 167 Jun 1 17:45 profiles.ini
[24+0]~$ mount | grep encfs
encfs on /home/itz/Private/firefox-profile type fuse.encfs
(rw,nosuid,nodev,relatime,user_id=1000,group_id=1000,default_permissions)
encfs is a fuse based filesystem, so that means everything under
firefox-profile is inaccessible to other users, including root.
When I give the --exclude-if-present option to duplicity, it tries to
locate that file underneath the symlink, even if
--exclude-other-filesystems is given as well. Leading to disaster:
[110+0]~# duplicity --encrypt-key C6FF61AD --use-agent
--exclude-other-filesystems --exclude-if-present .nobup --name
'matica!home!itz' /home/itz ssh://foolinux.lan/duplicity
Local and Remote metadata are synchronized, no sync needed.

duplicity should only check for the presence of --exclude-if-present
file under real directories, and not under symlinks to directories. It
should also skip this check if --exclude-other-filesystems is given as
well and the directory is a mountpoint.
