we would like to see Project Atomic images available to provision droplets with, for docker deployments and openshift "gear" they are the way to go, the boot times are extremely fast compared to a full blown fedora or centos image, they are more secure and rolling updates using the os-tree model makes it a no brainer for large clusters. http://www.projectatomic.io/ the fedora images are ready, centos images will be ready when centos 7 releases.

Project Atomic is backed by RedHat enterprise linux and the Openshift cloud stack.
