The temporary hostname is in each ARRAY line in mdadm.conf. As I
understand it, the temporary hostname is also in the superblock, and
these must match or I won't be able to boot. So, do I have to do
something about the superblock (how?), or just edit the name in the
ARRAY lines, or not touch it at all? I'm afraid to experiment
because my last encounter with "rescue mode" (trying to fix my
grub-install mess) didn't go very well.
Sorry to answer my own question, but a power failure caused a
corrupted filesystem on another computer and gave me a free IP to
experiment with. So, I went ahead and renamed my computer. I did
edit the name in mdadm.conf, and the system booted without
problems. ^^^^^^^^
