CentOS Stream was introduced in September 2019. In December 2020 it made news, raised a lot of questions and created long hand-wavy discussions and confusing arguments. During 2021 CentOS Stream 9 finally has found its place in the RHEL 9 development process. And now, in early 2022, we can take a good look at how it actually works. This talk is focused on the development process of the CentOS Stream distribution. We are going to talk about bootstrap, package updates, continuous integration, testing and contribution. We welcome distribution developers, but also users which are interested to know what's hidden under the hood of a typical enterprise-level system.
