GPT is not designed to be a sub-partitioning scheme. It can not be
used within a partition. As such, absolute block addresses are the
same as relative block addresses. As such, no mistake has been made
FreeBSD actually creates a GPT with relative addresses, which means
that if we allow it to be used to sub-partition partitions, it would
not have the same problem as the BSD label.
