Jie Yu commented on MESOS-6478:
-------------------------------
maybe we should just stop updating mtab for the work_dir mount and just use
fs::mount
> "filesystem/linux" isolator leaks (phantom) mounts in `mount` output

> 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?
