No, blkid does not print a "PARTUUID" value with an MBR. In only prints
"UUID" values, which as you noted, are _filesystem_ UUIDs. If you
want to use a filesystem UUID to locate the root partition, you need
an initramfs/initrd which contains an 'init' program that finds the
filesystem with the specified UUID, mounts that filesystem, and then
does a root_pivot.
