Michael Schroeder - OpenSUSE package management

This talk is about the package management stack in openSUSE and
its differences to Fedora. Package management is done through a
single library, libzypp, which itself uses the libsolv library
for dependency solving. Tools like zypper, YaST, or PackageKit
use libzypp to do the work, so the user always gets consistent
results.

As weak dependencies like "Recommends" or "Enhances" are becoming
a hot topic for Fedora as well, the talk will show how they are an
essential part of package management in openSUSE. They are used for
various purposes, like automatic installation of plugins, support
for package splits, language dependent packages, and hardware
dependent packages.

Another topic of interest is libzypp's vendor/arch locking mechanism.
Its purpose is to make sure installed packages do not switch to a
different vendor or architecture during an update, thereby losing
needed functionality. Libzypp also supports a "distribution
update" mode which turns off the update restrictions and tries to
emulate a fresh installation.

The talk will conclude by having a look at some other differences
to Fedora, like the way multilib is implemented in openSUSE or
package metadata is updated via a zsync delta algorithm.

Vratislav Podzmiek - The technology beyond Anaconda NewUI and 3rd party extensions for it

I would like to show the ideas and concepts behind the code that runs behind the Anaconda's new UI system. You will have a chance to learn about how we modularized the screens, moved to better data-UI separation and connected that to the rest of the anaconda submodules. I will also talk about the new firstboot and how it uses the new UI internals for sharing screens and achieving the same look and feel. The last part will discuss the API for 3rd party configuration and screens for anaconda and firstboot, which is something that was not possible before the rewrite and so is still under development.

Adrian Schröter - Open Build Service, possible use cases for Fedora

The Open Build Service (OBS) is a free (GPL licensed) infrastructure piece for Open Source Communities and larger in-house product development.

The session will show possible use cases including distribution development, continous integration, feature evaluation and more. This includes collaboration features between single developers in a local instance and collaboration between  projects via remote OBS instances.

I like to have also a BoF to discuss how Fedora could use OBS (or parts from it) and how package maintainership between openSUSE and Fedora could be improved.

Karel Klíč - Serious Bugs First: Automatic Problem Management in Fedora

Fedora would definitely benefit from having more bugs fixed, serious
bugs first.  We are presenting a client-server system which
facilitates problem reporting, monitoring and fixing.  The system
takes over many tasks that were previously performed by reporters,
quality assurance, and developers.  This leads to a notable increase
in the overall quality of Fedora.

Problems are automatically detected on users' computers via ABRT
client and reported to a Problem Tracker server in an anonymous form.
The server analyzes the user reports and sorts them by priority.
Package maintainers are asked to investigate top problems affecing
many users, and server assist them in the bug fixing.  Server tracks
the overall quality of Fedora and actions can be made depending on the
course.

Rainer Gerhards - Log Message Processing, Formatting and Normalizing with Rsyslog

Log messages become ever more-important, both in commercial settings for legal reasons as well as basis for anomaly and fault detection. Gathering log messages from diverse sources and making sense out of them is a though task - especially at high message rates. In this talk, we will describe rsyslog's message processing and re-formatting capabilities. Most importantly, we will show that a current syslogd is not just a dumb "file writing service" but rather a highly flexible and powerful tool that can do much more than simple log file processing. For example, it can also be integrated into complex workflows and normalization solutions. The talk offers a theoretical understanding of the relevant rsyslog design as well as practical examples, based on real-world use cases.
