This ends up being different than what landed in librsvg (that was imported into ostree) because in rpm-ostree we've basically been using `git archive`-based tarball generation rather than `make dist` for a long time. And supporting `make dist` looks like it'd get into handling the `libdnf` bits and walking into `cmake` land so...yeah let's not do that. The canonical sources are in git (recursively via submodule), except for the Rust sources, which cargo can download dynamically, and with this patch we support glomming all of that together into a tarball. (And turn off `make dist` so people understand how we do it) Tested by `make -f Makefile.dist-packaging dist-snapshot`, then copying the resulting tarball into a container with `--net=none` and building there.

rpm-ostree: A true hybrid image/package system
rpm-ostree combines libostree (an image system), with libdnf (a package system), bringing many of the benefits of both together.

Features:
- Transactional, background image-based (versioned/checksummed) upgrades
- OS rollback without affecting user data (
/usrbut not/etc,/var) via libostree - Client-side package layering (and overrides)

Projects using rpm-ostree
Project Atomic is an umbrella project for delivering upstream container technologies and combined with a minimized, atomically upgradable host system to Fedora, Red Hat Enterprise Linux, and CentOS.
rpm-ostree is the underlying technology for host updates. The headlining project is "Atomic Host", which is a server variant oriented towards running Linux containers using e.g. Kubernetes. However, there is now also a Workstation variant, showing the full generality of the rpm-ostree model.
