Yes, and very fast as well. Do note that if you (a) need to boot from a recovery CD and (b) have a low memory machine which really needs swap early, most of the ones I've tried don't use such a swap, you have to start it by hand. Also, I have not tried suspend to disk and restore using RAID-10, it's on my to-do list, but *way* down. But in general you will find it very fast and reliable. -- bill davidsen CTO TMR Associates, Inc Doing interesting things with small computers since 1979
