In general, I replaced Disk Id's of Ubuntu Gutsy by devices and is working great. I'm writing from my Gutsy destop.

A few weeks ago I lost my /home partition. As consultant, I also works in home therefore I don't have time for backup, thus I think is a good solution to have a RAID1.

First, I used Debian Etch, but it doesn't support easily my ATI Radeon 9200 video card, and caused problems with vmware.

I redo all the process but for Ubuntu Gutsy Gibbon 7.10, replacing the Disk ID's by devices. Also, for mnemotecnic reasons and easy recovery, I used md1 (boot) md2 (swap) and md5 (root).
