Practical Experience with Linux A/B Upgrades

Senior Software Engineer Leon Anavi discusses deploying software upgrades to fleets of embedded Linux IoT devices, using A/B redundant systems with two identical partitions using popular open source solutions (like Mender or RAUC). Although they provide great features out of the box there are still plenty of technical obstacles to overcome for real-world use cases. In this presentation, we walk through practical experiences using both Mender and RAUC with Yocto Project and OpenEmbedded. Leon discusses BSP integration and porting efforts for new devices, bootloader requirements and configurations, tips and tricks for ARM and x86-64 systems, read-only file systems, partition layouts, storing persistent data during upgrades, managing single-file artifacts, simultaneous setup with Docker and other containers.
