Customizing OS Images Using Container Technology

Discover how to customize operating systems using container-like techniques without building a new distribution in this DevConf.CZ 2024 conference talk. Learn about Fedora's image-based systems, including CoreOS, IoT, and Atomic Desktops, which offer atomic and reliable upgrades while allowing applications to run in containers or Flatpaks. Explore methods for modifying read-only system images to add hardware support, install security agents, or fix bugs. Understand how the distribution is being transformed into a container for building and distributing OS images, enabling users to modify Fedora images with custom packages, configuration files, and changes. Gain insights into successful projects like Universal Blue, Project Bluefin, and Bazzite that build upon Fedora Atomic Desktops without creating entirely new Linux distributions. Examine practical examples of this approach with Fedora CoreOS and Fedora Atomic Desktops in this 32-minute presentation by speakers Timothée Ravier and Jean-Baptiste Trystram.
