Hi,

I would suggest using something like that:

# zfs create -o mountpoint=none zpool/ROOT
# zfs snapshot zpool at be
# zfs clone zpool at be zpool/ROOT/default
# fetch https://github.com/vermaden/beadm/blob/master/beadm
# chmod +x beadm
# ./beadm list
# ./beadm activate default
# reboot

Be sure to use the latest *beadm* from one of these:
https://raw.github.com/vermaden/beadm/master/beadm
https://sourceforge.net/projects/beadm/

Let me know how these instructions work, especially if You got any errors or an unbootable system.

It would be best if You would test this zpool root to sys/ROOT/be transition under VirtualBox for 100% safety ;)
