There's no technical reason you can't have more than one jail using the same file system root, and even IP -- you'll find that ps(1) in one jail can't see processes in the other (and can't signal, etc) but otherwise works as expected. Of course, any given process has to be a member of at most one of the two. Robert N M Watson Computer Laboratory University of Cambridge
