[Bug 1034023] [NEW] add a nodevtmpfs option

[Serge Hallyn]

Public bug reported:

upstart is being modified to detect when certain /dev entries are not as
expected, and to mount a devtmpfs if so.  One of the entries being
checked is /dev/console.  In a container, /dev/console will not be as
expected (it will either be 136,X, or a symlink to /dev/lxc/console
which is 136,X).

LXC sets up the required device nodes and /dev/pts before starting init.
Therefore it would be nice to be able to simply pass init an option to
tell it not to bother mounting a devtmpfs.  Upstart could probably re-
use the existing 'container=lxc' environment variable (and the equiv for
libvirt).  Or it could use a new nodevtmpfs option.

** Affects: upstart (Ubuntu)
