You need some of the upstart services , this is how I worked through lucid containers, they mostly seem to work, although feedback is welcome:

http://blog.bodhizazen.net/linux/lxc-configure-debian-lenny-containers/
I am working through Fedora containers as well:

Although the Fedora stuff is still a bit rough.

Subject: [lxc-devel] lxc-start and lucid container
Hi all,
I have a slight problem using a lucid container (on a lucid host): if I
start the container via lxc-start, no console login starts up. I have to
use lxc-console from a differnet terminal. If I use a lenny container,
lxc-start shows the start up log messages and finally the getty/login.
I'm using the lxc-packages from lucid:

Any hints?
