Behind the Scenes of an Update Framework: RAUC

on YouTube ↗45m

" summary

RAUC is an image‑based update framework (v1.2) that automates creation, signing and atomic A/B slot switching while integrating with Yocto, Buildroot or PTXdist; the project has ~50 contributors and ~1,450 patches. Update bundles are squashfs with a manifest and CMS x.509 signatures, verified on‑device (supports PKCS#11 / HSM signing), handlers call mkfs/flash tools or run hooks, and bootloader interaction sets active/inactive slots. For network efficiency RAUC uses casync‑style chunking to stream and produce delta downloads.
