I see what Shykes is getting at though. I mean, if you want to use the rocket, then use the rocket. If you want to use docker, then how does adding another runtime help a docker user, when they could simply switch to rocket? I can understand how their might be a "convenience" factor, but if you're already actively deploying with docker images, then why bother with a separate image type?

Don't get me wrong, I think it's great the coreos guys are trying to make a bridge between the two projects, but so far, I don't see a need for this.
