Isar: Build Debian-Based Products with BitBake
summary
Isar assembles Debian binary packages with BitBake to produce ready-to-flash images: it creates a target chroot, builds custom .deb packages natively with dpkg-buildpackage, installs Debian binaries and project packages via BitBake recipes and outputs partitioned SD or rootfs images. It reuses Debian binaries and Yocto-style layering to manage multiple products and boards, parallelizes tasks to cut build time (example: full PC image in ~10 minutes), and minimizes package forking for long-term maintenance.
