[Lxc-users] 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:

0.6.5-1                                Linux containers userspace tools


The start trace is:

and the processes inside the container are:

CONTAINER  USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START

0:00 /sbin/getty -8 38400 tty1
root at ubuntu01:~#

(well, I disabled all upstart services but tty1)

Any hints?
