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.

• Client-side package layering (and overrides)
• Easily make your own: rpm-ostree compose tree and CoreOS Assembler
