[Bug 870832] Re: Plymouth not shown during live disk shutdown.

[Steve Langasek]

Well, one problem in the ubiquity-dm code is that it has no SIGTERM
signal handler.  So anything that causes ubiquity-dm to die by signal
(i.e., anything that causes upstart to want to stop the job, such as a
manual call to 'service ubiquity stop' or a runlevel change) does not
clean up the child processes... such as the X server.

This doesn't explain the behavior at the end of an install, because in
that case ubiquity-dm does try to shut down the X server before calling
reboot.  It might still be related to the race condition between
ubiquity-dm shutting down (thus no longer blocking the kdm job and
allowing it to try to start an X server) and the runlevel event being
propagated by the 'reboot' call.  If so, it might be possible to address
this by having ubiquity-dm not exit in the reboot case but instead wait
to receive SIGTERM.
