I'd like to embed structured metadata about the originating git repository. See [this example](https://pagure.io/fedora-atomic-host-continuous/c/142b12020d7efe18b56d039304efea102a210790?branch=master). However, I think what we really want here is a *single* value which has subkeys. One thing in the back of my mind too is...we could use this to enhance our "change detection". Right now we checksum the sack, treefile, and treecompose-post. But down the line, I'd like to support more sophisticated postprocessing, where the script might reference external files or the like. In that case, we could stop checksumming the post script, and rely on whether or not the git repo changed. (This would conversely mean we would do a build even if e.g. the repo's `README.md` changed, but we can address that with a post-assemble content check). Anyways though, for now, this gets us the ability to more easily drop more structured metadata in the commit, whether it's input git repos, tests that passed, etc. Note a trap that bit me here: since the metadata we write here is *host* endian, but `ostree show --raw` byteswaps (it needs to since the core ostree variant is always big endian), we get inverted numbers if the host is little. I think we should probably canonicalize our metadata to big endian; this should be pretty backwards compatible since I doubt anyone has been adding raw numbers so far.

rpm-ostree Overview
rpm-ostree is a hybrid image/package system. It uses OSTree as a base image format, and supports RPM on both the client and server side using libdnf.
For more information, see the online manual: Read The Docs (rpm-ostree)
Features:
- Atomic upgrades and rollback for host system updates
- A server side tool to consume RPMs and commit them to an OSTree repository
- A system daemon to consume OSTree commits as updates
Projects using rpm-ostree
Project Atomic uses rpm-ostree to provide a minimal host for Docker formatted Linux containers. Replicating a base immutable OS, then using Docker for applications.
