plymouth-upstart-bridge returns exit code 1, if
ply_boot_client_connect or ply_upstart_monitor_new fail.
Plymouthd uses abstract socket, so we can't be doing inotify watch on
the socket file.

How about this instead, see patch. Add start on or started plymouth,
or started plymouth-shutdown, and add pre-start exec to ping plymouth
and stop job from running if there is no plymouthd to talk to.

Title:
  plymouth-upstart-bridge main process (189) terminated with status 1 at
  boot

Status in “plymouth” package in Ubuntu:
  Confirmed

Bug description:
  I see this when I boot (I got it by running the dmesg command):
  [    7.631865] init: plymouth-upstart-bridge main process (173) terminated with status 1
  [    7.632154] init: plymouth-upstart-bridge main process ended, respawning
  [    7.670080] init: plymouth-upstart-bridge main process (183) terminated with status 1
  [    7.670443] init: plymouth-upstart-bridge main process ended, respawning
  [    7.706173] init: plymouth-upstart-bridge main process (186) terminated with status 1
  [    7.706534] init: plymouth-upstart-bridge main process ended, respawning

  I don't know if plymouth-upstart-bridge is supposed to be running at all time but it doesn't on my machine:
  bbigras at ubuntunew:~$ ps ax | grep plymouth-upstart-bridge
   8784 pts/2    S+     0:00 grep --color=auto plymouth-upstart-bridge
