Hi Shuai, I have a reviewboard still under review

Feel free to take a look or start afresh!
> Implement OverlayFS based provisioner backend

> Key: MESOS-2971
> URL: https://issues.apache.org/jira/browse/MESOS-2971
> Project: Mesos
> Issue Type: Improvement
> Reporter: Timothy Chen

>
> Part of the image provisioning process is to call a backend to create a root
> filesystem based on the image on disk layout.
> The problem with the copy backend is that it's both waste of IO and space,
> and bind only can deal with one layer.
> Overlayfs backend allows us to utilize the filesystem to merge multiple
> filesystems into one efficiently.
