A lot of history here. Long before the YAML treefiles, I was dissatisfied with the JSON treefile syntax, and also wanted to create a format that could be used by the (still experimental) `container` builtin, and chose to use GKeyFile. I don't think that really worked out; the Rust YAML is just way better. In the future we probably want to more cleanly split off the "compose only" aspects of the treefile. But for now, it's rather tedious to pass down flags from the treefile into the keyfile/gvariant. Let's just give direct access to the treefile to the core. Prep for sysusers.

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.
+-----------------------------------------+
| |
| rpm-ostree (daemon + CLI) |
+------> <---------+

| | pkg layering, initramfs --enable | |

+-----------------|-------------------------+ +-----------------------|-----------------+
| | | |
| libostree (image system) | | libdnf (pkg system) |
| | | |
| C API, hardlink fs trees, system repo, | | ties together libsolv (SAT solver) |
| commits, atomic bootloader swap | | with librepo (RPM repo downloads) |

Features:
- Transactional, background image-based (versioned/checksummed) upgrades
- OS rollback without affecting user data (
/usr
but not/etc
,/var
) via libostree - Client-side package layering (and overrides)
- Easily make your own:
rpm-ostree compose tree
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.

Talks and media
A number of Project Atomic talks are available; see for example this post which has a bigger collection that also includes talks on containers.
