Couple other things to note: Alternatives creates symlinks in /usr, and that is a read-only space for Atomic Host. Will need to modify "alternatives" in order to use it on AH. Something to track.
Docker Engine will have multiple parts with runc, containerd, dockerd, docker client by the time we get to the 1.12 upstream release. The pattern of mounting /usr/bin/docker into the container will no longer be sufficient. ________________________________ From: Daniel J Walsh Sent: May 10, 2016 10:00 To: The CentOS developers mailing list.

The only thing that is shared between them is the socket the listen on since they provide the same API. At the last second we were asked to add the switch to allow /usr/bin/docker to work with both. (I am now thinking this might have been a mistake.)
