[lxc-users] "lxc.mount.auto=cgroup:mixed" not working anymore?

[Stéphane Graber]

You may talk to the socket directly over DBus using any of the existing
DBus libraries in your favorite language.

You may look at what cgm is doing (it just calls dbus-send) and then do
the equivalent in whatever language you want directly using DBus.
