Behind the Scenes of an Update Framework: RAUC

Explore the inner workings of RAUC, a robust update framework, in this comprehensive conference talk. Dive into the recommended chain of steps for creating and signing updates, verifying authenticity, and automatic slot selection in A+B setups. Learn how RAUC abstracts complex aspects of building a reliable update system, simplifying integration to storage layout configuration and update bundle creation via Yocto, Buildroot, or PTXdist. Discover key design decisions, solutions for atomic bootloader updates, streaming delta updates, UI integration, and HSM usage for signing key protection. Gain insights into data migration, verified boot in the context of updating, and potential future enhancements for RAUC. Explore topics such as fail-safe updating, code and service architecture, slot handling, update bundle format, bootloader interaction, authentication features, and integration with various ecosystems.
