Most of these solutions (and RAID IDs and UUIDs) don't completely
solve the problem; they just push it to a different time: how do you
talk about a new disk, or a new RAID array, or a moved disk? And what
about removable media (not neglecting the possibility of multiple
drives)? Removable media from another OS? Shared drives?

Not that this kind of "firm" ID might not be an improvement, or at
least a good sanity check.

[Side question, not original with me: why isn't all this a 2.5 discussion?]
