Colin Walters	906a8a14e0	jigdo2commit: Change input to repoid:name ... Let's "repo bind" the OIRPM by default; this makes the rpm-md repo feel a lot more like an ostree remote, and IMO is just a really good idea in general to increase predictabilty.

Colin Walters	694b798c73	Introduce experimental "rpm-ostree jigdo" ... Tracking issue: https://github.com/projectatomic/rpm-ostree/issues/1081 To briefly recap: Let's experiment with doing ostree-in-RPM, basically the "compose" process injects additional data (SELinux labels for example) in an "ostree image" RPM, like `fedora-atomic-host-27.8-1.x86_64.rpm`. That "ostree image" RPM will contain the OSTree commit+metadata, and tell us what RPMs we need need to download. For updates, like `yum update` we only download changed RPMs, plus the new "oirpm". But SELinux labeling, depsolving, etc. are still done server side, and we still have a reliable OSTree commit checksum. This is a lot like [Jigdo](http://atterer.org/jigdo/) Here we fully demonstrate the concept working end-to-end; we use the "traditional" `compose tree` to commit a bunch of RPMs to an OSTree repo, which has a checksum, version etc. Then the new `ex commit2jigdo` generates the "oirpm". This is the "server side" operation. Next simulating the client side, `jigdo2commit` takes the OIRPM and uses it and downloads the "jigdo set" RPMs, fully regenerating *bit for bit* the final OSTree commit. If you want to play with this, I'd take a look at the `test-jigdo.sh`; from there you can find other useful bits like the example `fedora-atomic-host.spec` file (though the canonical copy of this will likely land in the [fedora-atomic](http://pagure.io/fedora-atomic) manifest git repo.
