Normally, fsck is able to automatically handle the problem after a dirty shutdown. In all the dirty shutdowns I've seen, I've only had to manually run fsck maybe twice. As far as the power sit is concerned: if you have a UPS and you don't have some sort of monitoring software to gracefully shutdown the machine during extended outages, you're shooting yourself in the foot! Kind of like getting a car with all the fancy safety features so you can drink a bottle of vodka before you drive. Regardless, isn't this the reason background fsck was developed in 5? > What's more, even if you CAN boot into single user mode and run > fsck, it can be frustrating.

Doesn't happen all that often to me. -- Bill Moran Potential Technologies http://www.potentialtech.com
