Jonathan Lebon 33ea6fbc96 daemon/upgrader: Reuse sack from core for advisories 
In #1344, we changed `upgrade` to always write the cached update. One
thing I hadn't noticed was that with pkglayering, loading the sack twice
meant we printed all that gory repo info twice.

Really, the much nicer thing to do is just to make an effort to try to
*keep* the original sack that the core used so that we skip all that
overhead completely.

Closes: #1357

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.

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.

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