Practical Experience with Linux A/B Upgrades
summary
Practical guidance for reliable embedded Linux updates using Mender and RAUC, built with Yocto Dunfell and tested on Raspberry Pi and x86-64. Mender provides free A/B updates (delta updates require paid plans), a default 128 MB data partition and a single-file artifact mode for app patches; RAUC requires ext4/SquashFS, U-Boot/GRUB boot scripts and signed bundles. Meta-rauc-community supplies ready examples; meta-virtualization shows how to combine A/B base upgrades with containerized apps for cleaner app rollouts.
