bootc has transformed how we can consume operating systems.
Where does this leave the "enterprise workstation"? There may not me a lot of us, but we have some great use cases that need to be filled. Join me as I go over "Bluefin LTS" - a CentOS based workstation. Can it compete with it's Fedora cousins? Can we have our cake and eat it to? Stability AND freshness?
In this talk we'll go over the lessons learned from building a desktop for cloud native developers and some of the feedback we've received. (There's some good eatin' over here.)
- title: "Proposed Updates SIG: Bridging the Gap between development and production" slides: https://gitlab.com/CentOS/promo/centos-events/-/raw/main/2025-04-showcase/cpu-sig.pdf youtube: DK1_UwaNvGU speakers: - name: Michel Lind - name: Jonathan Write desc: |CentOS Stream is especially suited for production deployments. In these environments it's often common to develop improvements to distribution packages and want to contribute them upstream. Unfortunately, until very recently that required one to then maintain their own build and deployment pipeline for the packages, at least until the changes made their way into the distribution.
CentOS Proposed Updates (CPU) SIG aims to bridge this gap - changes that have been submitted as merge requests can be built in this SIG, providing those who run Stream in production with access to needed updates while they make their way into CentOS Stream. We hope this will help increase collaboration between RHEL engineers, CentOS Stream contributors, and the rebuild community as well, especially those that have distributions derived from CentOS Stream directly (such as AlmaLinux with AlmaLinux OS Kitten), as everyone can focus on making improvements without reinventing their own build pipelines.
- title: "RPM Copy-on-write" youtube: YMR2-PMx-Kc speakers: - name: Matteo Croce desc: | RPM CoW (Copy-on-Write) leverages filesystem reflink capabilities to perform package installations with minimal I/O overhead. This significantly reduces disk usage, speeds up deployment, and frees space due to the deduplication. This method integrates seamlessly with modern filesystems that support reflinks, such as XFS and Btrfs. - title: "Building AutoSD images for the Automotive industry" slides: https://gitlab.com/CentOS/promo/centos-events/-/raw/main/2025-04-showcase/autosd.pdf youtube: YXqJTtNIIYc speakers: - name: Leonardo Rossetti desc: | I would like to share how the CentOS Automotive SIG builds its images for the automotive industry (aka AutoSD - Automotive Stream Distribution), the reasons behind doing it this way while introducing the tool that does it all: automotive-image-builder.CentOS Showcase is a half-day virtual event that showcases the work happening in the CentOS ecosystem. It features short talks focusing on CentOS Stream, the CentOS SIGs, and various projects that build on the work done in CentOS.
