Look, I'm not new to FreeBSD. I know all of this.

A normal FreeBSD system without softupdates on the root or boot partition should come right back up without a manual fsck. In my experience, if softupdates are used on the root partition and the root partition doubles as the boot partition then you'll have much more difficulty recovering from a power failure. -- Jesse Guardiani, Systems Administrator WingNET Internet Services, P.O.
