 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.
