How does it look like everything is read only from inside the jail? The fact that a
"df" only shows the root filesystem and not all your others file systems?

Your report of great success is encouraging. I've never done this and
sometimes you don't see the full consequences when you haven't done
something before.
I think you understand my question. It's the fact that mount(8) report
read only. If you looked at that, you would conclude that you had no
write access at all. Well, I set up the jail, so I can see behind the
curtain. A downstream user that never saw behind the curtain wouldn't
know where they could write a file unless they simply guessed.
That is why I asked about jailbreaking. There is information crossing
the jail in a mysterious way. The jail reports that everything under
root is read only, but the jail can still see the read-writeness of the
invisible (to mount) null filesystems.
From the sound of it, this is expected behavior.
