Does it really need to be implemented ?? zfs root with ufs /boot is
working great.

Personally I push a minimal install onto the ufs partition then
dump-restore onto tank when created...  I keep the data on the ufs
partition and just link in boot directory into the tank;
http://wiki.freebsd.org/ZFSOnRoot

You can even gmirror the ufs partition between HDD's

If the zfs ever messes up, you still have a workable system available
via the ufs partition.

I don't fully see the advantages of a fully zfs system including
the /boot.

Thanks
