Before, every docker image had three extra layers: 1. A `closure` layer which is an internal implementation detail of calculating the closure of the container 2. a `name-config.json` layer which is the images' run-time configuration, and has no business being *in* the image as a layer. 3. a "bulk-layers" layer which is again and implementation detail around collecting the image's closure. None of these layers need to be in the final product.
