I built an atomic image with docker and docker-latest, uncommented the
line `DOCKERBINARY=/usr/bin/docker-latest` in `/etc/sysconfig/docker`,
and restarted the docker service, and then `sudo docker info`

Error response from daemon: client is newer than server (client API
version: 1.22, server API version: 1.21)

Then it occurred to me to stop the docker service and start the
docker-latest service, and that seemed to work fine. We definitely
need docs around this.

One thing that occurs to me is that 1.10 isn't the latest docker...
