@Paul, Ah, I see!

The component drives in a RAID-1 array have the _same_ UUID, so I would
assume that a line in /etc/mdadm.conf such as:

ARRAY /dev/md0 UUID=d3176595:06cb3677:46406ca7:d12d146f

would identify _both_ component drives.  This is what the output of
mdadm --examine --brief --scan --config=partitions would imply.

I'll try this.

I'm not fond of UUID's.  They're hard to read and impossible to copy by
hand without making mistakes!
