Largely they can't, I did try it once and it was very confusing and I
very nearly trashed my main filesystem.
On i386 (etc) a disk can have multiple type 169 mbr partitions (so that
the mbr_bootsel code can select between different filesystems), but the
netbsd disklabel always describes the whole disk. For safe-keeping it
is written to the start of ALL the type 169 mbr partitions, although
the kernel will normally read it from the booted partition.
