Well, the UUID is absolutely stable in general -- most people install
one Linux and never change it.  AFAIK nothing else should cause it to
change.

Using the UUID means that your system will work if the layout of disk
devices changes -- that way when your devices are moved from hdX to sdX
in the transition to libata, or when you rearrange your SATA cables or
add another controller ... things still work.
