Not entirely. On some ports `installboot' is a no-op (since the
secondary bootstrap isn't pinned); on other ports, installboot updates
the primary. A restore (say), or an interrupted upgrade, or developer
hacking, could leave a disk with both old, and new bootblocks (/boot
and /boot.${MACHINE}).

Which one does the primary load?
