             Summary: Linux 'MountTable' not sorted as expected
                 Key: MESOS-5969
                 URL: https://issues.apache.org/jira/browse/MESOS-5969
             Project: Mesos
          Issue Type: Bug
    Affects Versions: 1.0.0
            Reporter: Kevin Klues
            Assignee: Kevin Klues
             Fix For: 1.0.1


Many places in the codebase assume that the mount table is sorted according to the order: {{parent mount point < child mount point}}.

However, in some cases this may not be true if (for example), a parent mount point (say {{/}}) is remounted to add some extra flags to it.  When this happens, the remounted file system will appear in the mount table at the point where it was remounted.

We actually encountered this problem in the wild for the case of {{/}} being remounted after {{/run}} was mounted -- causing problems in the {{NvidiaVolume}} which assumes the {{parent  < child}} ordering.
