the first of these. You can find out all valid major numbers by
looking into include/linux/major.h.
+In addition to major and minor numbers, if the device containing your
+root partition uses a partition table format with unique partition
+identifiers, then you may use them. For instance,
+"root=PARTUUID=00112233-4455-6677-8899-AABBCCDDEEFF". It is also
