Hey, so upstream Fedora has been working on this: https://pagure.io/pungi And I'd like to discuss trying to use it for Atomic Host work. The concept of a "compose" that ties together the ISO and cloud images is nice for example. It's going to need to gain some more sophistication around OSTree, and there'd likely be some details that need changing such as how signing happens. But having a common codebase here would be nice, and I think we could also stop doing this in Jenkins for https://wiki.centos.org/SpecialInterestGroup/Atomic/Devel too. (We'd retain the auto-generated RPMs at least though)
