[sf-lug] server reboot

[Michael Paoli]

Unless I'm in some great rush, I'm often more inclined to
do something like:
# (cd / && umask 022 && echo 'shutdown -r +2' | batch)

That at least gives anyone that happens to login between when
one checks if anyone's logged in, and start of the shutdown command
execution, a 2 minute warning.  It also allows oneself 2 minutes to
change one's mind ... "just in case".

I'll also often include reasonably informative message, e.g.:
# cd / && shutdown -r +10 '
> '`hostname`' rebooting to test [whatever...]
> '
#
