Ditto. I ended up using the same approach with a script called from
rc.local - "late" didn't work for me because /dev/zvol wasn't there yet.
This was in the first release of FreeBSD that included zfs.

I believe the rc.local workaround is still in use on the system in
question (now running CURRENT).
