"dd ..." should preserve the UUIDs but you can get the UUIDs from "blkid". -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?

You can clone it (better from Clonezilla or at least from a non-live system) and then edit the needed files from a LiveCD.
