It has never occured to me to check, but you could also specify arrays by
"name=" there, instead of UUID. See "man mdadm.conf".

and the name is *what*

Name is, see mdadm --detail /dev/md1 | grep Name

ARRAY /dev/md1 UUID=b7475879:c95d9a47:c5043c02:0c5ae720
ARRAY /dev/md2 UUID=ea253255:cb915401:f32794ad:ce0fe396
