Overlayfs Driver for Docker Mounts

I want to share a tool I've been using recently, which I think is fantastic.

It's an OverlayFS driver for Docker that lets you mount a host machine folder into your containers. The cool part is that it behaves like a volume, allowing the container to modify the folder's contents, but these changes remain isolated to the containers that use that volume.

It shares the same semantics of a Docker container, so it's pretty usable, I'm using it so much that I'm surprised this is not a default driver in docker.
