Everything looks right to me.  I've tried it out on my own system, and
it worked as expected.  The only difference is I don't have VIMAGE, so
I commented out the vnet stuff (including the exec.start that goes
along with it).

So maybe the trouble is with vnet?  Even still, that looks correct.
I'm just able to test it at the moment.  Regardless, vnet shouldn't
affect the nullfs mount.

What output do you get for "jail -vr testjail1"?
