I just wanted to confirm... judging by this solution, I assume that for
your situation, the partition UUIDs were in fact changing when you
duplicated the disks?

If this is the case, it makes me a sad panda (or...confused, which may
be more appropriate here)... as I was under the impression, as someone
else pointed out, that duplicating the disk should preserve the
partition UUID... therefore making this a non-issue... 

So, I suppose my question is this: How is the duplicator actually
duplicating the hard drives? Is it a bit-for-bit copy process? a
straight partition copy? something like a RAID mirroring process? I do
know that at the very least, the latter-most option does duplicate UUIDs
(at least in my experience) since the drives are treated as the same
device...allowing you to boot from either copy...

I ask this question mainly for posterity, but also out of sheer
curiosity. Maybe you could provide a link to your duplicator's spec
sheet so I could research it myself? (or if you don't want to for
trade-secret reasons or whatever, a duplicator similar to it?) thanks!
