rpm-ostree: A true hybrid image/package system

rpm-ostree is a hybrid image/package system. It combines libostree as a base image format, and accepts RPM on both the client and server side, sharing code with the dnf project; specifically libdnf. and thus bringing many of the benefits of both together.

🆕 as of release 2022.16 rpm-ostree now also supports ostree native containers.

Features:

• Transactional, background image-based (versioned/checksummed) upgrades, using both bootable container images as well as an "ostree native" HTTP model
• OS rollback without affecting user data (/usr but not /etc, /var) via libostree
• Client-side package layering (and overrides)
• Custom base images via rpm-ostree compose image (container) or rpm-ostree compose tree (ostree repo)
