The RPMs are created in Koji from specfiles in dist-git. The images come in different formats, but have in common creation in Koji from kickstart files — this includes the official Fedora Docker Base Image. This change introduces a new type of image, a Docker Layered Image, which is created from a Dockerfile and builds on top of that base image.

Is this an F23 or an F24 change proposal? I thought the deadline to propose F23
changes was June 23rd.
