Well, after timing each of the steps at shutdown, most steps take a
second or less. Shutting down apache only takes 2-3 seconds, so I don't
really buy much from turning that daemon off. The big time sinks are
(1) stopping rsyslogd (~14 seconds), (2) unmounting the local file
systems (~11 seconds), and broadcasting halt to all processes (~5
seconds). Unfortunately, it doesn't seem like a good idea to do away
with any of those steps.

Thanks, everyone. I know I can do away with apache, but I don't really
know what all of the other daemons are doing. I guess it's time to
learn. I know I need sshd and dhcpd, and I figured that syslogd was
probably a good idea. I had also assumed that crond, and inetd were
probably required. That doesn't leave much else to turn off, but I'll
look into it more. I appreciate all of the suggestions. I know I could
just cycle power or force a halt, but I don't want to end up with file
system corruption, so shutdown seems to be the most graceful way to do
it. Alas, a minute can be a long time for a user in the field to wait.

First analyse exactly what you need to run, e.g. sshd, your_app, etc
Then
in the rc2.d directory move all SNNapp and KNNapp for the stuff you DONT
need running to No_SNNapp and No_KNNapp.
Then re-time shutdown.
I always stick to the TSimage (not the Debian image) because it is so
minimal. I add what I need, then I know what needs doing for shutdown.
In fact shutdown usually only involves killing some daemons then
umount'ing
and filesystems then halting.
