Hmm, I think I saw this warning on more recent ZFS.

All in all we currently print this when we upgrade root pool we print
the following:

	If you boot from pool 'foo', don't forget to update boot code.
	Assuming you use GPT partitioning and da0 is your boot disk
	the following command will do it:

		gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 da0

(Note, that bootfs property doesn't have to be set to boot from a pool.)

We should print similar information when:

- We set bootfs property.
- Add new vdev(s) to root pool.
- Attach new vdev(s) to root pool.
