I haven't tried this ... but I plan to real soon now :-).

	To bring the system (down) to single-user for unattended
	backups, try leaving a semaphore via cron or at:

		cat /dev/null >/mymessage
		/etc/reboot

	In one of your rc files put something like

		if [ -f "/mymessage" ]; then
			rm -f /mymessage
			# Hmm, security hole? vvvvv
			/run/your/dump/backup.shell
			# or run your C program with exec(dump).
			/etc/reboot
		fi
