I thought it was something like this I saw somewhere :D

I'd like it to be mounted rw - did you mean that ro is the only
correct option or can it be either?

so - in a guest poudriere instance, if i make the mount for
/usr/poudriere to be on an imported p9fs, but with respect to the
host this would be on a ufs fs without seperate mountpoints. 
It'd be able to make all of its tmp dirs etc below /usr/poudriere
on demand, if I understand correctly.
