Comment 17 for bug 1824407

I think kernel already generates some faked up UUIDs, i.e. i think there is something for like FAT and DOS partition table, either fs uuid, or like partition table uuid, partition uuid, partition type uuid, some such.

They are "shorter" than normal, and less unique, but at least something.

Should we request squashfs userspace tooling and kernel to start having a UUID in the squashfs?

We do use squashfs a lot, all the snaps and all the installer media.
