Just for any case, I would really love to solve this, I accept the fact that it is connected with upgrading the modules but this just is no reason for breaking backward compatibility.

root> zpool --version

zfs-0.8.4-1

zfs-kmod-0.8.4-1

root> ll /.zfs/snapshot

But nevermind, this is something that was working since zfs as root was brought into FreeBSD (and we are talking about FreeBSD not ZoL), never had issues about it.
