Hi, Chris,
This isn't an answer to your question, but is it possible to get
a
UPS system? Then you could run powerd (power daemon from
www.sf.net), and I think they have circuit breakers too.
Buying an UPS is in my plans but, because of burocratic problems, I'll
have to wait several weeks for it. For now, I have to rely on the
file system.
Thanks,
Marcelo
