First Experiences with the Embedded Debian Build System Isar

summary
Isar combines Debian binary packages with bitbake-style layers to produce a bootable SD image (QEMU and Raspberry Pi were used) and can build kernels from upstream git by adding Debian metadata, producing a final image in about 10 minutes for typical setups. Workflows include multistrap rootfs assembly, packaging custom apps as .deb or building them inside the chroot, and image partitioning/bootloader placement. Current rough edges: image generation requires root, some recipes don’t re-run reliably, and no general cross-build path so native builds can be slow.
