The Unified Kernel Image in openSUSE distribution (osc25)
### Introduction: The Need for Secure and Reliable Booting In the ever-evolving landscape of Linux distributions, security and boot reliability have become paramount concerns. Traditionally, the boot process relied on separate kernel and initrd components, leading to potential vulnerabilities and complexities. This presentation delves into the journey of integrating a more robust and secure boot mechanism by leveraging the Unified Kernel Image (UKI). ### Static and Signed Initrd: Establishing a Foundation for Integrity We will begin by outlining the critical need for a static and signed initrd within modern Linux systems. The dynamic nature of traditional initrd...
The Great Migration? (Part 1) (osc25)
Recent global political events have up ended the global order. Coupled with the EOL of Windows 10, does Desktop Linux have a shot at the mass replacement of Windows in the corporate and government sectors? This wide ranging talk will cover the reasons why I think it does, and how we might achieve this goal. I believe it is easier than we think.

SELinux - current state in (open)SUSE (osc25)
SELinux is a Mandatory Access Control (MAC) system that enhances a system's security by enforcing policy-based access control rules. For a long time openSUSE and SUSE have relied heavily on AppArmor as default MAC system. With the decision to switch to SELinux as default MAC on SLE 16 and openSUSE Tumbleweed, there are multiple challenges that we have to overcome to integrate SELinux into those distributions. This session will give an overview on the current state of SELinux in openSUSE and SUSE, the plans for the future and what it means for users. Licensed to the public under...
What It’s Like to Study with Linux (osc25)

Fine tuning log routing (osc25)
Do you want to detect threats real-time and easily search logs to find relevant information? By default, incoming log messages are treated in log management apps as one long string. This is good enough if you just want to store logs. However, if you also want to act on log messages, you need more structured information. Syslog-ng and other applications also let you parse log messages. While parsing structured logs, like JSON, is easy, unstructured logs need a lot of work. This is where sequence can help you: if you have enough logs to...
"Public Money? Public Code!" (osc25)
‘Public Money? Public Code!’ under this slogan thousands of individuals and hundreds of organisations come together and advocate for Free and Open Source Software in public institutions. Together with over 230 organisations the Free Software Foundation Europe (FSFE) is calling for public institutions to publish publicly financed software under a Free and Open Source Software license - If it is public money, it should be public code! The long-term goal of the initiative is to recognise and reduce the software dependency and vendor lock-in of public administration and to make public administrations digitally independent...
Atomic OS Updates via OCI Images (osc25)
When using tools like RPM or Zypper for updating packages, there is a risk of incomplete updates or breaking the running system. To overcome these challenges, we have developed **container-snap**, a prototype plugin designed to deliver **atomic OS updates** that are fully applied or rolled back without compromising the system's state. **container-snap** leverages OCI images as the source for updates and integrates seamlessly with openSUSE’s [tukit](https://github.com/openSUSE/transactional-update) for transactional OS updates. By utilizing **Podman’s btrfs storage driver**, it creates bootable btrfs subvolumes directly from OCI images, effectively turning them into atomic OS snapshots. This allows you...
Leap 16.0 Beta (osc25)
openSUSE Leap is a "traditional" community distribution built on
binary packages from SLES. In this session, we'll dive into the
recently released openSUSE Leap 16.0 Beta, exploring its new features
and changes. We'll also cover the migration process from Leap 15,
including any challenges or considerations to keep in mind.
