54 * 64 disklabels start at offset 0 on the disk or slice they reside. All
55 * values are byte offsets, not block numbers, in order to allow portability.
56 * Unlike the original 32 bit disklabels, the on-disk format for a 64 bit
57 * disklabel is slice-relative and does not have to be translated.
