I have submitted a new package (consisting of a kind of old python binding) to factory a while ago. The package, called python-lxc-python2, contains the python2-bindings for lxc, so that ansible can use its lxc_container module to interact with lxc containers.
The code is quite old and has not been touched in quite some time, but I guess this is due to it being finished and feature complete. Works flawlessly in my tests, if not feel free to speak up.
I see this has been auto-submitted to 42.3 already, so I do not need to SR. Nice.
Kind Regards, Johannes
