Subject [jira] [Commented] (MESOS-6478) "filesystem/linux" isolator leaks (phantom) mounts in `mount` output
Date Tue, 25 Oct 2016 16:44:58 GMT

    [ https://issues.apache.org/jira/browse/MESOS-6478?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15605819#comment-15605819
] 

Jie Yu commented on MESOS-6478:
-------------------------------

maybe we should just stop updating mtab for the work_dir mount and just use fs::mount

> Of course these don't exist and they are gone from {{/proc/mounts}} but I imagine these
could look scary when after running the agent for a while. Perhaps we can improve the Mesos
mount utility to take care of these so they don't leave these traces?
