Column 1 in /etc/fstab identifies which partition is to be mounted. Identifiers need to be unique. Device names in /dev/ are no longer stable, they can and do move around and change. User-defined labels are a good choice but users can and do re-use the same labels. All filesystems generate a GUID for themselves and these are guaranteed to be unique in the universe, so simply put it in column 1 and mount will never ever get it wrong. Ubuntu takes this approach to be able to give guarantees about installers. It works well. Until you find you want to edit fstab by hand. -- Alan McKinnnon alan.mckinnon@gmail.com
