[Bug 863864] Re: /etc/init/failsafe.conf doesn't actually stop on runlevel

[Clint Byrum]

Raised to High, this also causes odd problems with plymouth in boot, and
shows the message if lightdm takes more than 20 seconds.

Title:
  /etc/init/failsafe.conf doesn't actually stop on runlevel

Status in “upstart” package in Ubuntu:
  Triaged

Bug description:
  The failsafe job is meant to inform the user that the system is
  waiting for the network to come up, and start the runlevel if a
  timeout is reached.

  However, the 'stop on runlevel' does *not* work as designed, because
  all the activity here is done in the pre-start script which upstart
  will not kill when the job target changes to stop:

  $ sudo start failsafe&
  [1] 3979
  vorlon at nvidia-8600m:~$ status failsafe
  failsafe start/pre-start, process 3981
  vorlon at nvidia-8600m:~$ sudo stop failsafe&
  [2] 3985
  vorlon at nvidia-8600m:~$ status failsafefailsafe stop/pre-start, process 3981

  failsafe stop/pre-start, process 3981
  [1]-  Done                    sudo start failsafe

  So the pre-start script continues sleeping, and continues sending
  messages to plymouth.

  If you happen to reboot the system within two minutes of startup, this
  results in the messages being printed on the splash screen at
  *shutdown*, which is rather confusing.

  To avoid this, I think the failsafe job should be switched to do its
  work in 'script' instead of 'pre-start script', and rc-sysinit changed
  to listen for an event emitted by the failsafe job at the end of this
  script instead of on 'started failsafe'.
