I would not rely on that because lxc may evolve to not use the cgroup if
not present.

If you use upstart, you can check the 'container=lxc' env variable in
the udev init script in order to know if you are in a container.
Otherwise for sysvrc init, I don't know how to handle that.
If the container does not support handling uevents then
/sys/kernel/uevent_helper should not exist. This is how openvz behaves.

At the first glance udev events are supported in the container. But for the sake of optimization, I recommend to not use it as it will trigger the events in all the containers.
