The Fedora 45 Sausage Factory

Fedora's release process begins when packagers push code to Git repositories, which triggers Koji (the build system) to construct reproducible builds from specific commit hashes. The article outlines how Fedora 45 transforms source code through various systems—starting with dist-git repositories managed via fedpkg, then through Koji's hub-and-spoke architecture that ensures clean, reproducible builds. This walkthrough documents the complete pipeline from source code to final artifacts like ISOs, cloud images, and container images, with plans to update it as the Fedora 45 release process evolves.
