I posted it here to this list, looking for recommendations.
The only update I have for it is that freebsd-update doesn't work
as ZFS doesn't yet support chflags.  Other than that I am very happy
with this setup.  Can't wait for ZFS to mature to the point for this
to work flawlessly.

Here it is again

#zpool create pool

#zfs create -o mountpoint=jails pool/jails

	looking for a work around

Install ports or package that all jails will require, such as bash and
vim-lite


#exit
