Exploring RAUC: A Flexible Building Block for Image-Based Updates (asg2023)

Published: Sept. 14, 2023, 1:15 p.m.

b"Recently, atomic updates via image based systems have become more relevant for\\nservers and desktops, as they allow predictable management of large fleets. In the\\nembedded Linux space, this approach has been the default for many years and\\nproven updaters exist already.\\n\\nIn this talk, we will delve into RAUC and look at how its design and features\\nhave been driven by the requirements for robust, atomic updates.\\nThe presentation will introduce the fundamental concepts surrounding A/B fallback\\nand update signing in the context of embedded Linux updates.\\nWe will then explore the commonalities and differences between RAUC and systemd's\\nsysupdate.\\n\\nThe discussion will progress to cover RAUC's bundle-based update system, which\\nallows for comprehensive system updates without the need for local storage,\\nthanks to HTTP streaming. Additionally, we will demonstrate how adaptive updates\\nminimize download sizes without necessitating version-specific patch management.\\nabout this event: https://cfp.all-systems-go.io/all-systems-go-2023/talk/NEQ9TX/"
