Ok now I have played with sysutils/ezjail, forget the first part ;)
just "ezjail-admin install" will do a binary install for a base jail
from an ftp server.
you can use "ezjail-admin update -u" to update the base jail using
freebsd-update for some reason this isnt in the manpage.
Not exactly what you have asked for but close enough if you dont like
installing from source.
