Hm.  Here's a thought: if he's logging in on the console, init might be
using a a file descriptor bound to the device node _outside_ the chroot.
I can think of a few ways chaos could then ensue, given subtle bugs in
the session-handling or device alias detection code...

This kind of problem is why I've never been comfortable having init do
the chroot for this sort of system configuration, FWIW.
