Both really good ideas.

I'm also reminded, by your mention of partition labels, of a real
stumper of a problem that was described many years ago on the Silicon
Valley Linux User Group mailing list: A Linux host kernel panicked and
fell over any time a particular hard drive was physically attached to it
during boot up, but the hard drive was well behaved and had normal,
apparently valid Linux filesystems on it, as viewed on other Linux
hosts or using a live CD distro.

The solution was that the afflicted host had a partition with label of,
say, USR_PART, and the seemingly problematic hard drive also had one
with the identical label string. The booting kernel got confused and
died because of the ambiguity, when it tried to parse and implement
/etc/fstab.

You did, of course, say _unique_ partition labels, which avoids that
gentleman's quite perplexing problem.
