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...
Swift Deployment and Faster Releases (osc25)
This session explores the utilization of parallelism and rolling updates within Ansible playbooks to expedite deployment processes and facilitate faster releases. As organizations strive for agility and efficiency in their software delivery pipelines, optimizing deployment strategies becomes crucial. By leveraging Ansible's parallel execution capabilities and implementing rolling updates, teams can reduce deployment times and minimize downtime, thereby enhancing overall release velocity. This session provides insights into the benefits and techniques of employing parallelism and rolling updates in Ansible playbooks to achieve swift deployment and accelerate software releases.

Linux schedulers for fun and profit with SchedKit (osc25)
The Linux kernel scheduler is a critical component, profoundly impacting system performance and responsiveness. Traditionally, changing the scheduler has involved recompilation, rebooting, or complex kernel module management – a significant barrier for experimentation and fine-grained performance tuning. SchedKit dramatically simplifies this process, enabling users to dynamically switch between schedulers at runtime, without reboots or kernel modifications, opening up new possibilities in customizing kernel scheduling for the specific usecase. This talk introduces SchedKit, a new open-source project leveraging the power of eBPF and the sched_ext framework. SchedKit allows users to leverage custom Linux...

A Community has to do what a Community has to do! (osc25)
When proprietary products are discontinued or bought up by competitors, your own (decision-making) freedom can quickly become precarious. A discontinued product forces you to migrate, incurs costs, and imposes unwelcome decisions. Not so with open source software: it offers me the freedom to develop the code further at any time, either on my own or with new partners, and to set up new support chains. The freedom not to have to migrate and the freedom not to have to work with an unpleasant service provider. Even drastic changes in product and business strategy can be...
Update from the Future Technology Team (osc25)
In this presentation, I will give an introduction to the projects that the Future Technology team is working on and report on the current status.
Some of the bigger topics are:
- Update on Full Disk Encryption with TPM and Fido2
- Adding grub2-BLS support:
- YaST2
- Images (including with full disk encryption)
- Making it the default
- Adding FDE+TPM support to YaST2
- New features for transactional-update and rework of /etc handling
- systemd-sysext on MicroOS
- systemd-pull and OBS
- New tools (e.g. sndiff)
- And much more

"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...
Integrating Uyuni with Ansible and Terraform (osc25)
Uyuni offers two powerful APIs (XMLRPC and JSON) to integrate additional third-party applications. This talk demonstrates two integrations that allow users driving infrastructure automation: - an [Ansible collection](https://github.com/stdevel/ansible-collection-uyuni) that integrates Uyuni into Ansible and Event-driven Ansible. It allows controlling managed systems and enables users to continue using pre-existing Ansible environments such as AWX or Ansible Semaphore. Using this, fully automated patch management workflows are possible. - [a Terraform / OpenTofu provider MVP](https://github.com/svalabs/terraform-provider-uyuni) that can create resources within Uyuni I'd like to use this session to discuss how we can improve third-party integrations for Uyuni - e.g. by...
