What does the resulting image look like?

Would it be enough to generate an “Image JSON Description” in this
format: <https://github.com/docker/docker/blob/master/image/spec/v1.md>?

I’m not familiar enough with Docker but I’m under the impression that we
should be able to generate an image without even using Docker.  :-)

Thanks for sharing the neat hack!
