So here's the issue - maybe I'm missing something. If I configure apcupsd to shutdown on power fail and the power really stays off till the apc unit shut down, my machine will reboot on power up. But what if the power comes back once the daemon has started the shutdown? What is needed is a guaranteed power cycle from the apc unit - which AFAIK is not an option. So I just use the apc to cover short outages and prevent power bouncing which I know from experience can cause damage. When the battery goes flat I get a hard powerfail shutdown which modern linux tollerates quite well - yeah for journaled file systems. Marc Auslander
