That's it! Thank you! I didn't report back sooner because I've been
testing, testing, testing.
I have one last raid-related question. I'm going to have to rename this
computer, because it's a replacement for another computer (running Linux
for 7 years without a hitch, time to retire) so I'll shut down the old
computer and give the new one its hostname and IP address. I've done
this before, so I do know I have to update /etc/hostname,
/etc/interfaces, my exim configuration, etc. Only the part about RAID
is new to me.
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.
