night-time auto-reboot?

The linux side is easy, you just put an entry in root's crontab like this:
0 6 * * 1-5 /sbin/lilo -R dos; /sbin/shutdown -r

This will reboot the machine into the 'dos' operating system at 6:00 am each
Monday to Friday morning.

In windows 2000, you can use the SHUTDOWN.EXE command from the windows 2000
resource kit called from the Scheduled Task manager.  The command should be
called as follows:
	shutdown  /l  /r /y /t:5 /c
	/l = local
	/r = reboot?
	/y = yes
	/t = time
	/c = close(?)

With lilo set up to boot Linux by default, the machine will boot into Linux
when called from windows 2000, and the cron script will make sure that the
machine boots into windows when rebooted via cron.
