# The ui job post-stop script depends on a variety of daemons to be
# up and running during shutdown. In general, those daemons run
# from jobs that use 'stop on stopping boot-services'. In general,
# if a job says 'stop on stopping fubar', the job's 'post-stop'
# script runs *after* the the main process for 'fubar' is already
# dead. So, to guarantee correct operation, the 'ui' job can't use
# 'stop on stopping boot-services'.
# We use this job to delay 'stopping boot-services' until after the
# 'ui' job cleans up. The basic operation is this:
# + The 'ui' job stop conditions prevent this job's 'started'
# event until the 'post-stop' script completes.
# + This job stops itself with its own 'started' event.
# + The 'stopping boot-services' event doesn't happen until
# all of the preceding steps complete.
