Building Linux Images from Scratch - Image Builder and Configuration Layers

Explore the intricacies of building Linux images from scratch in this DevConf.CZ 2023 conference talk. Delve into Image Builder, a tool for creating bootable OS images of Fedora, CentOS, and RHEL across multiple versions, hardware architectures, and cloud environments. Learn about the challenges of managing numerous configurations while ensuring minimal usability. Discover the three-layered approach to image customization: baseline configuration, target environment setup, and user-provided modifications. Gain insights into recent efforts to formalize these abstractions, represent them in code, and improve user accessibility. Speaker Achilleas Koutsou discusses the team's journey in reimagining image definitions and creating a comprehensive universe of possibilities.
