I'm still not clear which UUID was changed. Even if you change the
firmware image,[1] the filesystem UUID should not change, because that
would require changing the filesystem.
[Pretty much anything which changes the partition UUID can also change
the partition label, though perhaps whatever did the update doesn't
change the label.]
But in any event, LABEL works just as well.
