Switch Raspberry Pi builds from proprietary firmware direct-boot to a firmware → U-Boot → GRUB → kernel chain using GPT partitioning: - GPT partition layout with fixed UUIDs matching os_install: firmware (128MB), ESP (100MB), boot (2GB FAT32), root (btrfs) - U-Boot as the kernel in config.txt, chainloading GRUB EFI - Pi-specific GRUB config overrides (console, USB quirks, cgroup) - Btrfs root with shrink-to-minimum for image compression - init_resize.sh updated for GPT (sgdisk -e) and btrfs resize - Removed os-partitions from config.yaml (now derived from fstab)
StartOS Image Recipes
Code and debos recipes that are used to create the StartOS live and installer
images.
If you want to build a local image in the exact same environment used to build
official StartOS images, you can use the run-local-build.sh helper script:
# Prerequisites
sudo apt-get install -y debspawn binfmt-support
sudo mkdir -p /etc/debspawn/ && echo "AllowUnsafePermissions=true" | sudo tee /etc/debspawn/global.toml
# Build image
./run-local-build.sh
In order for the build to work properly, you will need debspawn >= 0.5.1, the build may fail with prior versions.
