ah, but that UUID is actually fat serial number / volume-id

Sets the volume ID of the newly created filesystem; VOLUME-ID is a 32-bit hexadecimal number (for example, 2e24ec82). The default is a number which depends on the filesystem creation time.

It would be nice if squashfs had UUID support, and like blkid /dev/loop* printed them, and kernel used them, etc.
