zpool upgrade's message is not very smart.  I think it just uses hardcoded paths
and a hardcode drive.  (For example, it always says da0 even if you have
a mirror in which case you should update the bootcode on all of the devices.)

I have a fresh install of 12.0-RC3 here that still has the files in /boot
and doesn't have a /bootpool directory at all.
