There are ways to configure the newworld machines to reboot automatically
upon power restoration after power failure (It was one of the setup
questions in the setup assistant; it is also in the energysaver cdev).
This sets a flag, which obviously must involve the OF system, which reboots
the machine on power-restoration. You can set OF to automatically go to
yaboot, and yaboot can be set to auto-launch ydl. Post-failure bootup is
automatically going to check for losses; the daemons should be autolaunched
if configured properly on your system.
If you have an appropriate ups, you can set linux up to automatically shut
itself down safely when the ups detects power failure. APS has linux
drivers, and mac drivers, but I haven't looked into those as I can't afford
their products. (They charge an extra US$100 for the mac version of
Powerslide....)
