Colin Walters 2bc8d7cccb upgrader: Prune pkgcache repo 
Until now, we weren't pruning the pkgcache repo at all.  I ran out of
space in the root partition in my CAHC vagrant test box, so it's time
to fix this.

The basic algorithm is to walk over the full rpmdb contents of each
root, generate a set of "currently referenced" cached refs, then delete
any refs in the pkgcache repo which aren't included.  Then, do a prune
of the pkgcache repo.

While we're here, factor out a `sysroot_upgrader_cleanup()` function
which does all of the cleanup.  The idea is at some point we need to
introduce an `rpm-ostree cleanup` command or so which calls this, to
handle the case where the system is interrupted post-deploy but
pre-clean.

Closes: https://github.com/projectatomic/rpm-ostree/issues/428

Closes: #437

rpm-ostree Overview

rpm-ostree is a hybrid image/package system. It uses OSTree as a base image format, and supports RPM on both the client and server side using libhif.

For more information, see the online manual: Read The Docs (rpm-ostree)

Features:

  • Atomic upgrades and rollback for host system updates
  • A server side tool to consume RPMs and commit them to an OSTree repository
  • A system daemon to consume OSTree commits as updates

Projects using rpm-ostree

Project Atomic uses rpm-ostree to provide a minimal host for Docker formatted Linux containers. Replicating a base immutable OS, then using Docker for applications.
