Jonathan Lebon fa5be441b1 libpriv/rpm-util: Group by SRPMs when printing changelogs 
I've become quite fond of the `--changelogs` switch lately on my
Silverblue. I find it useful as a first step when nailing down a
regression, or just to peruse the churn of changes after an update.

One annoyance is that the same changelog gets printed multiple times for
each RPM that shares the same SRPM. This patch does a naive lookahead to
dedupe them. Example output:

```
  NetworkManager 1:1.12.6-4.fc29.x86_64 -> 1:1.12.6-5.fc29.x86_64
  NetworkManager-adsl 1:1.12.6-4.fc29.x86_64 -> 1:1.12.6-5.fc29.x86_64
  NetworkManager-bluetooth 1:1.12.6-4.fc29.x86_64 -> 1:1.12.6-5.fc29.x86_64
  NetworkManager-config-connectivity-fedora 1:1.12.6-4.fc29.noarch -> 1:1.12.6-5.fc29.noarch
  NetworkManager-libnm 1:1.12.6-4.fc29.x86_64 -> 1:1.12.6-5.fc29.x86_64
  NetworkManager-ppp 1:1.12.6-4.fc29.x86_64 -> 1:1.12.6-5.fc29.x86_64
  NetworkManager-wifi 1:1.12.6-4.fc29.x86_64 -> 1:1.12.6-5.fc29.x86_64
  NetworkManager-wwan 1:1.12.6-4.fc29.x86_64 -> 1:1.12.6-5.fc29.x86_64
    * Mon Jan 14 2019 Beniamino Galvani <bgalvani@redhat.com> - 1:1.12.6-5
    - improve Wi-Fi PMF support (rh #1665694)
```

I say "naive" because this doesn't catch the case where a binary RPM is
named differently enough that they're not consecutive. Anyway, this
simple heuristic cleans up the output nicely.

Closes: #1738

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.

Talks and media

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