Funnily enough, I never got on with ezjail and I just configure them 
with a few lines in rc.conf. I believe that ezjail is useful if you have 
a high number of jails running, and you want to manage them. If you only 
have a few and can edit a text file. The handbook Chapter 15 has all the 
information you need; possibly a bit too much!

The concept is that you just make a directory, copy what you want to in 
it (like all the files on a live FreeBSD system), add a few lines 
describing it to rc.conf (i.e. the name, directory and IP address you 
want to pass through) and "run" it using "jail". Yes, you can do an 
buildworld+installworld if you want to get the environment in that way 
but it's just a bunch of files. I'm happily running "images" of earlier 
FreeBSD systems in jails on later ones - the main box I use for this 
happens to be 9.0 running 7.x and 8.x systems.

I can't see what you're trying to do with ezjail, but I don't know 
ezjail at all well. Feel free to email me directly if you have a 
specific problem.
