How do we detect > unambigiously if lxc is in use? I strongly recommend a more generic approach of detecting whether the required mount is already mounted, and skipping the operation if it is. This has two advantages: - this isn't specific to lxc, but will correctly handle any other (theoretical) cases where the mounts are handled prior to initscripts. - if the lxc environment doesn't match the initscripts expectations, there will still be a suitable error message at boot about the failure to mount any mounts that are missing. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
