The `devicemapper` storage driver is deprecated in favor of `overlay2`, and will be removed in a future release. Users of the `devicemapper` storage driver are recommended to migrate to a different storage driver, such as `overlay2`, which is now the default storage driver. The `devicemapper` storage driver facilitates running Docker on older (3.x) kernels that have no support for other storage drivers (such as overlay2, or AUFS). Now that support for `overlay2` is added to all supported distros (as they are either on kernel 4.x, or have support for multiple lowerdirs backported), there is no reason to continue maintenance of the `devicemapper` storage driver.

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.

The `aufs` storage driver is deprecated in favor of `overlay2`, and will be removed in a future release. Users of the `aufs` storage driver are recommended to migrate to a different storage driver, such as `overlay2`, which is now the default storage driver. The `aufs` storage driver facilitates running Docker on distros that have no support for OverlayFS, such as Ubuntu 14.04 LTS, which originally shipped with a 3.14 kernel. Now that Ubuntu 14.04 is no longer a supported distro for Docker, and `overlay2` is available to all supported distros (as they are either on kernel 4.x, or have support for multiple lowerdirs backported), there is no reason to continue maintenance of the `aufs` storage driver.

Is this going to be merged to v18.09? |
|
Let me close this for now; there were concerns about AuFS still being too widely in use to mark it deprecated already 😕 |
