Cool. Should have thought about that. I'd still personally build ext3 into the kernel (ie non-modular), simply because it's always going to be in use. Modules have some overhead.

wrt to your UPS situation, if you have an APC UPS then check out apcupsd. apcupsd will run in network mode, so one UPS can trigger multiple machines. Runs fine on *nix and Win.
