Thank you for the explanation. Would regular Fedora contributors be able to create and build Layered Docker images using OSBS? Or will this be usable only for the official images produced as part of Fedora Products? E.g. if I think it would be beneficial to ship some package/service that is already shipped in Fedora as Docker image, will there be any way for me to leverage OSBS instance in Fedora? It is not entirely clear to me who is the intended consumer of this - Fedora releng? Fedora WGs? Regular contributors? Thanks.
