Benjamin Mahler created MESOS-713:
-------------------------------------

             Summary: Support for adding subsystems to existing cgroup hierarchies.
                 Key: MESOS-713
                 URL: https://issues.apache.org/jira/browse/MESOS-713
             Project: Mesos
          Issue Type: Improvement
          Components: isolation
            Reporter: Benjamin Mahler
            Priority: Minor


Currently if a slave is restarted with additional subsystems, it will refuse to proceed if
those subsystems are not attached to the existing hierarchy.

It's possible to add subsystems to existing hierarchies via re-mounting:

We can add support for this by calling mount with the MS_REMOUNT option.
