Description Wendy Cheng 2005-06-21 11:34:24 EDT
Description of problem:
There are merits of specifying root filesystem in grub using UUID since disk
label doesn't fit the need. For example, in a real world case, when a panic
system got rebooted, it picked up the wrong lun (root partition) from the shared
SAN since someone just newly created a new root partition (lun) for another host
using the very same disk label. It took a while to figure out what went wrong
because the system was panicked before that reboot.

UUID has the downside of being completely incomprehensible to a user :)

LABEL is the best compromise between something that can be understood and
something that is relatively resilient to disks moving around.
