“A/B Linux updates with RAUC and meta-rauc-community: now & in the future” by Leon Anavi

RAUC is a safe and secure open source software solution for A/B updates of embedded Linux devices. It supports the Yocto Project and OpenEmbedded, Buildroot and PTXdist. Upgrades are performed through RAUC bundles which can be installed either through the network or using the old-fashioned way with a USB stick. In 2020 layer meta-rauc-community was created to provide examples how to integrate the lightweight update client RAUC on various machines. Initially it supported Raspberry Pi. In 2021 the layer was moved to the RAUC organization in GitHub and over the time it was ported to new machine, including sunxi (Allwinner) and qemux86-64. The presentation is appropriate for anyone interested in software upgrades. We will talk about the evolution of meta-rauc-community and provide guidelines for porting to new machines using Yocto and OpenEmbedded BSP layers.
