GPT seems better than MBR for partition labels.
GPT labels should be independent of file system.
GPT labels are useful in /etc/fstab to get around fstab tyranny where, because
of multiple disks, partition number designations might not come out right.
NetBSD-current can identify such a partition as NAME=nb7usbamd64-1 (or
whatever).
FreeBSD could access this partition as /dev/gpt/nb7amd64-1
This is a whole lot better than traditional BSD disklabels, where the various
BSDs can't read each other's disklabels.
