I think shutdown should be reserved for programs that save state
between instances or otherwise would cause a "cleanup" operation to run
then next time they are started after an unclean shutdown.  Adding
shutdown to things like amd, mountd, moused, etc. simply forces what
would be done in init's final SIGTERM sweep to be done sequentially
instead of in parallel.  Also, if any of those daemons doesn't want to
immediately exit for some reason (amd hanging on a stuck mountpoint,
for example), it increases the likelyhood of the global shutdown timer
expiring and force-killing other daemons that might have wanted the
chance to shut down cleanly.
