Re:Edgy Eft "UUID's" in fstab

That analysis is rather paranoid.

Most filesystems, with only a few exceptions, include a UUID in them when formatted. This has been the case for years.

The only other common identifying piece of information is the LABEL.

You can mount filesystems (in<nobr> <wbr></nobr>/etc/fstab) with either UUID=... or LABEL=..., one could have

LABEL=users<nobr> <wbr></nobr>/home ext3 defaults 0 0

in there to mount any filesytem with the LABEL "users" on<nobr> <wbr></nobr>/home.

Obviously LABELs aren't that unique, and are often blank -- so for the automatic conversion they weren't that useful. To make sure the automatic conversion was reliable, and didn't suddenly cause people's drives to dance, we used the filesystem UUID instead of the LABEL.

You can change it to LABEL= if you like; or even just to<nobr> <wbr></nobr>/dev/hd* again -- but then don't file bugs when the device name changes
