The `overlay` storage driver is deprecated in favor of the `overlay2` storage driver, which has all the benefits of `overlay`, without its limitations (excessive inode consumption). The legacy `overlay` storage driver will be removed in a future release. Users of the `overlay` storage driver should migrate to the `overlay2` storage driver. The legacy `overlay` storage driver allowed using overlayFS-backed filesystems on pre 4.x kernels. Now that all supported distributions are able to run `overlay2` (as they are either on kernel 4.x, or have support for multiple lowerdirs backported), there is no reason to keep maintaining the `overlay` storage driver.

Aside from this PR, can we deprecate AUFS as well? |

Yes, aufs could definitely be a candidate as well, now that support for Ubuntu 14.04 is dropped (which, I think was the only distro that actively used it) |

Warning can go in a separate PR, getting these docs in is good. |
