summary
Shows how to convert a Yocto/Poky image into an OTA-updatable device using OSTree and the meta-sota Yocto layer, with a working demo on Raspberry Pi and QEMU. Uses OSTree content-addressed commits (SHA-256), incremental HTTP fetches, A/B boot via U-Boot, and hardlinks to avoid full double-size copies. Provides an open-source Rust and C++ client plus a Dockerized server (SaaS option at ~$1/device, first 20 free). Builds succeed and devices check in, report hw and packages, and receive staged rollouts.
