Every image records the identity of its build inputs. forgefirm-manifest.bbclass gives a component recipe a per-file source fingerprint (git ls-tree blob ids, submodules recursed; file:// sources hashed with git hash-object); the kernel and glowforge.ko publish theirs through do_deploy because kernel-module-split leaves the module recipe's main package empty. forgefirm-image-manifest.bbclass assembles the entries with the platform identity - machine, modules directory, device tree hashes, layer content hashes (meta-forgefirm and the meta-openglow layers by content, the kas-managed layers by revision) - into /etc/forgefirm-manifest.json and deploys a copy next to the image. Layer revisions and dirty flags stay outside the identity, so a rebuild from an unchanged tree keeps its content hash and the release and dev images of one build share it. The acceptance tool and the release gate read this file.

# ForgeFIRM image manifest: kernel identity (forgefirm-image-manifest.bbclass
|
|
# collects it from DEPLOY_DIR_IMAGE). The kernel tree is too large to list
|
|
# per file and every acceptance test depends on it anyway, so the entry
|
|
# carries the pinned revision and the hash of the configuration actually
|
|
# built as pseudo-files ("@srcrev", "@config") that the fingerprint globs
|
|
# match like any other path. Device-tree sources and config fragments come
|
|
# from the BSP layer, which the image manifest hashes by content.
