Setting up Yocto Layers and Builds with Official Tools – 2023 Edition
summary
Official Poky tools record and reproduce Yocto builds by saving build config as a template and layer layout as a JSON plus a self-contained Python setup script. Commands shown: bitbake -c layers save buildconf (saves local.conf and bblayers.conf into a layer template), bitbake layers create-layer-setup (writes JSON and a bootstrap script), and use oe-init-build-env to recreate a build from a template. Templates live in a product layer (example: AlexisGizmo), layers must be committed (no uncommitted changes), and tools land in recent Poky/master.
