By default, mkfs.erofs will sue the current date to set some metadata in the filesystem it generates, and will also use generate a random UUID for that filesystem. This is not reproducible. When BR2_REPRODUCIBLE is selected, set the filesystem timestamps to $SOURCE_DATE_EPOCH, and the filesystem UUID to the nil uuid (as good as any other arbitrary one).
