UUIDs are attached to the file system and are stable. In the case above, you have a new file system, so you get a new UUID. UUIDs and LABELs are not unique though. LVM snapshots (and similar technologies) can result in two file systems have the same UUID and LABEL. -- Boyd Stephen Smith Jr. ,= ,-_-. =. b...@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
