resolveCGroupController :: Text -> IO (Controller a) Source #
Resolve a cgroup (v1) controller by name, as viewed by the current process
see cgroups(7): /proc/self/cgroup is a file that contains information about control groups applied to this process
see proc(5): /proc/self/mountinfo is a file that contains information about mounts available to this process
Throws an Exception when the controller is not able to be found, or when running outside of a cgroup
