Docker is not supported. /var/lib/docker/aufs will be excluded in next
update.

Title:
  different dir is used for backups after docker is installed

Status in TimeShift:
  New

Bug description:
  After installing docker (on Ubuntu 16.04 LTS), timeshift switches to
  using directory '/var/lib/docker/aufs/timeshift/' for keeping
  snapshots, instead of normal '/timeshift/' (and doesn't see old
  snapshots anymore).

  Most probably, that's because docker registers a new mount point at
  /var/lib/docker/aufs path for the same device as / - e.g. my
  /proc/mounts (apparently loaded by Device.vala) has the following
  entries, in order as shown:

  $ cat /proc/mounts | grep vg-root
  /dev/mapper/ubuntu--vg-root / ext4 rw,relatime,errors=remount-ro,data=ordered
0 0
  /dev/mapper/ubuntu--vg-root /var/lib/docker/aufs ext4
rw,relatime,errors=remount-ro,data=ordered 0 0

  Please note I've excluded /var/lib/docker/*** in /etc/timeshift.json,
  otherwise this resulted in endless recursion, exhausting all available
  disk space on the device.
