A practical walkthrough of using Bootc and OSTree to manage Linux systems as immutable, versioned deployments. OSTree is explained as 'Git for filesystems', enabling atomic updates, rollbacks, and version tracking. Bootc extends this by treating the OS as an OCI container image, allowing you to build a Containerfile-based system image, generate ISOs or QCOW2 images via bootc-image-builder, and push images to a registry like Harbor. A CI/CD workflow using GitHub Actions automates image builds on Containerfile changes, and a built-in systemd timer service checks for and applies new images every 4 hours. The post also covers the drift problem that arises from manually installing packages with rpm-ostree outside the image build process, and why all changes should go through the OCI image pipeline to maintain consistency.
