Ok, I used the tklpatch to get a openvz/lxc  tar file from the 13.0RC 64bit iso file... it is just a bit larger than the iso.

Basicly clean up rc*.d startups, confconsole disabled (luckily no upstart anymore), replaced rsyslog with syslog-ng, removed unneeded packages, added inithooks interactive.d and moved some interactive firstboot.d scripts to interactive.d 

I will check on monday if its running nicely on lxc (then I have access to a 64bit machine with lxc installed, I don't have openvz)...

OK, works like a charm

I have now got a TKL13.0RC 64bit running in Virtualbox and inside I have running in a LXC container another TKL13.0RC 64bit.

Removed the shellinabox and webmin in the container. Only thing is that the shutdown and reboot hangs, so it needs some debugging.

But overall..... nice, realy nice...
