haosdent commented on MESOS-3430:
---------------------------------
Thank you very much! Ubuntu 14.04 (ext4) also have the problem like this if
mark the root as shared mount point. Is it would more simple to use make-slave
to stop propagate between mount points. So that we don't need concern about the
outside environment. Assume someone use make-private/make-shared to change the
root mount point during the slave running.
