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. -- Don Armstrong https://www.donarmstrong.com Identical parts aren't. -- Beach's Law
