I have noticed in some distros (namely Ubuntu) that the fstab uses
UUID's rather than /dev references. Is this a better way?
Does it eliminate the problem of /dev references changing when
another drive, i.e., an external USB drive, is plugged in? The
/dev references may change but the UUID's in fstab wouldn't, would
they?
Correct. UUIDs are universally unique (as the name already
"suggests" *g*)
and thus, there cannot be a clash.

Any chance that GRUB will ever use these? I have a sata hd carrier
and when I reboot with it plugged in, grub sees the disk order
differently and gives me problems (I either have to get a grub
command line and boot manually or use a Grub boot floppy).
As long as your BIOS is passing off control to the correct drive when
both are plugged in a boot, what about using GRUB's fallback feature?
Say your bootable partition is normally (hd0,0), but with your
external drive plugged in the proper partition becomes (hd1,0)
instead. You can duplicate your GRUB config with (hd1,0) for the
root entry and specify that as a fallback option. Then as long as
GRUB gets control your system is still bootable.
If the BIOS is trying to boot off the removable drive, I suppose you
could install GRUB on it too with a similar setup, but that obviously
doesn't scale well beyond a single computer with a known boot
configuration.
Interesting! This Fallback feature of GRUB bears investigation. Thanks.
