Just a small note (not about configuration).  File descriptor #0 is used
by lxc-start to save tty parameters.  It does not work currenlty anyway
(since it re-opens fd#0 later), but redirecting fd#0 externally like this
does not help to fix this bug ;)

But with fd#0 redirected we're losing console input completely.
