Power flickers are common after an outage, so having the system automatically power up after an outage could lead to the power to cutting out while you're in the middle of fsck'ing your file systems. This is very bad juju, and something you don't want to happen. Trusting the facility generator got me into that one once, which is the only time in the last decade I've had a file system fried beyond the point of restoration. http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
