Right now if we want to lock e.g. systemd, we need to specify every subpackage of systemd that we use. This is a lot of duplication because in the majority of cases, what we really mean is "lock at this build of systemd". Since RPMs bake in the source RPM they were built from, we can use this to lock packages more succinctly. See the testcase and #2676 for examples of how this looks. Closes: https://github.com/coreos/rpm-ostree/issues/2676
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.
