How We Added Software Updates to AGL
Talkat Embedded Linux Conference + OpenIoT Summit North America 2017 · on Thursday, 2017-02-23· at 14:30· Broadway III/IV·
summary
Adds OTA updates to AGL early in development by using OSTree dual-like deployments with incremental, content-addressed objects and hardlink sharing so only deltas transfer. Integrates into Yocto as a new image class and a meta-sota/meta-agl-extra layer that moves writable data into /var, performs three‑way /etc merges, and creates bootable deployments with U‑Boot chainloading for Raspberry Pi, QEMU and MinnowBoard. Update client is implemented in Rust, supports configurable rollbacks (default 2), server-side incremental uploads, and is used for CI-delivered updates.
