Package: lxc
Version: 0.8.0~rc1-8
Severity: normal
Dear Maintainer,
I could not get a console from the container with neither lxc-start nor
lxc-console after setting up a debian sid container.
The only way to access the container was with ssh.
sudo lxc-create -n sid -t debian
# choose sid and wait for container build process
sudo lxc-start -n sid
The output of the lxc-start is
---8<--------

And there is no console. After a while some new output:
---8<--------

INIT: Id "3" respawning too fast: disabled for 5 minutes
INIT: Id "2" respawning too fast: disabled for 5 minutes

Even with lxc-console:
---8<--------
miguel@quartor:~$ sudo lxc-console -n sid
Type <Ctrl+a q> to exit the console, <Ctrl+a Ctrl+a> to enter Ctrl+a itself
---8<--------
After some digging about this I've found that this could be some debconf
settings in live-config that are not working:
root@quartor:/# debconf-get-selections |grep lxc
unknown live-debconfig/sysvinit/lxc-consoles string 6
unknown live-debconfig/sysvinit/lxc-enable boolean false
I've tried to use a preseed file to set lxc-enable to true and create a
new container but it had no results. The new container still had
lxc-enable false.
Then I've looked to backends/debconf/0030-sysvinit in live-config source
code. Then I've edited the /etc/inittab in the container and the
relevant part was this:
---8<--------
1:2345:respawn:/sbin/getty 38400 tty1
2:23:respawn:/sbin/getty 38400 tty2
3:23:respawn:/sbin/getty 38400 tty3
4:23:respawn:/sbin/getty 38400 tty4
5:23:respawn:/sbin/getty 38400 tty5
6:23:respawn:/sbin/getty 38400 tty6
---8<--------
After editing those lines to the following and restarting the container
I could get a console right after lxc-start.
---8<--------
1:2345:respawn:/sbin/getty 38400 console
c1:23:respawn:/sbin/getty 38400 console
#c2:23:respawn:/sbin/getty 38400 console
#c3:23:respawn:/sbin/getty 38400 tty4
#c4:23:respawn:/sbin/getty 38400 tty5
#c5:23:respawn:/sbin/getty 38400 tty6
---8<--------
I've reported this to lxc package because I'm not sure if this is a lxc
debian template problem or if it is only a live-config package problem.
Decided to report to lxc because it was where the issue came up. Please
reassign if necessary.
Thank you
