- artifacts: introduce `ARTIFACT_IGNORE_CACHE=yes` - artifacts: introduce `DONT_BUILD_ARTIFACTS`, list of artifacts that if not found cached, fail the build - kernel_package_source() is no more - a long dissertation about kernels, families, and the universe - artifacts: actually use rootfs artifact for image build - artifacts: detangle via artifact_base_dir - artifacts: rootfs: use folders in artifact_name; include cache_type - artifacts: some cleanups / validations - rootfs artifact; drop old rootfs cli - artifacts: new CLI shortcuts; remove old firmware CLI - artifacts: full firmware & usage - use firmware artifacts in image build and install its debs - kernel artifact sans legacy; use tmpdir for .deb target for all packages - legacy artifact versions is no more; pack/unpack now in common obtain; - artifacts: uboot: cleanup legacy renaming, use artifact version directly - artifacts: add firmware (small) artifact - deploy uboot to loop from artifact; allow tty to artifact; todos for cleaning - fixes, kernel dtb/headers conditional; remove `.git` from Makefile url; use mapfile for finding files to hash - completely remove KERNEL_HAS_WORKING_HEADERS_FULL_SOURCE and `kernel_package_callback_linux_headers_full_source()` - don't use realpath for artifact_file_relative - curb some warnings - fix: only install headers & dtbs if such exist - kernel .config hook modification hash versioning - OCI_TARGET_BASE vs per-artifact defaults; only deploy to remote from CLI with OTB - artifact revolver & installing into image - add artifact_map_packages and artifact_map_debs dicts - revolver accumulates all info - REPOSITORY_INSTALL is no more (for uboot/kernel, later others) - rename `VER` to `IMAGE_INSTALLED_KERNEL_VERSION`
