I <believe|hope> that this is the answer to my original question. I use
a desktop computer which has served me adequately for some 5 years! HBAs
and Fibre Channel loops (after checking out what they are on the
Internet!) are well and truly over my horizon.

If that were the whole story, I might not have written for advice. But
I was under the impression that the UUID mapping also needs to be
extended to all the entries in /etc/fstab. On my setup, these are numerous!

There is a great deal more info in the reply that is well beyond my
current <understanding|competence>. But if my assumption - flagged
above - is correct, then I believe that I can safely remain in my state
of blissful ignorance.
Again, thank you for taking the time to help me to make sense of the
Debian release notes.
