Yes, pid 1 within the namespace at least. I couldn't find anywhere where
upstart opened /dev/console without O_NOCTTY set either, but evidently
it is happening somehow.

I just looked though, and this doesn't seem to be happening for actual
pid 1, only pid 1 in containers. The container is saucy and the host is
trusty, but they both have upstart 1.11-0ubuntu1.
