summary
Step‑by‑step recipe to get an ostree-enabled Yocto Raspberry Pi 4 image: build with Yocto meta-updater, create ostree commits (refs/logs/content checksums), serve via HTTP or use the ostree-push tunnel (DB Nicholson) to publish, pull specific commits or static deltas (example delta 245 KB) to devices, and deploy with ostree admin (upgrade/rollback/deploy/unlock/hotfix). Covers pull/push/offline/distributed modes, u‑boot+initramfs boot flow, examples that add htop/nano/jq and a production claim of over one million devices.
