When only light files changed since the last full lb build (Go source, overlay scripts/configs), the build is now automatically done in ~5-8 min instead of 30+ min: - unsquashfs existing squashfs from prior build - rsync overlay-stage on top - mksquashfs repack (zstd, same block size) - xorriso ISO repack with -boot_image any replay (preserves EFI/MBR hybrid) Heavy changes (VERSIONS, package-lists, hooks, archives, Dockerfile, auto/config) still trigger a full lb build. Tracking is via a marker file (.bee-full-build-marker) written after each successful full build. No change to build-in-container.sh or the full build path.

ISO Build
bee ISO is built inside a Debian 12 builder container via iso/builder/build-in-container.sh.
Requirements
- Docker Desktop or another Docker-compatible container runtime
- Privileged containers enabled
- Enough free disk space for builder cache, Debian live-build artifacts, NVIDIA driver cache, and CUDA userspace packages
Build On macOS
From the repository root:
sh iso/builder/build-in-container.sh
The script defaults to linux/amd64 builder containers, so it works on:
- Intel Mac
- Apple Silicon (
M1/M2/M3/M4) via Docker Desktop's Linux VM
You do not need to pass --platform manually for normal ISO builds.
Useful Options
Build with explicit SSH keys baked into the ISO:
sh iso/builder/build-in-container.sh --authorized-keys ~/.ssh/id_ed25519.pub
Force a clean rebuild of the builder image and build caches:
sh iso/builder/build-in-container.sh --clean-build
Use a custom cache directory:
sh iso/builder/build-in-container.sh --cache-dir /path/to/cache
Notes
- The builder image is automatically rebuilt if the local tag exists for the wrong architecture.
- The live ISO boots with Debian
live-boottoram, so the read-only medium is copied into RAM during boot and the runtime no longer depends on the original USB/BMC virtual media staying present. - Target systems need enough RAM for the full compressed live medium plus normal runtime overhead, or boot may fail before reaching the TUI.
- The NVIDIA variant installs DCGM 4 packages matched to the CUDA user-mode driver major version. For driver branch
590/ CUDA13.x, the package family isdatacenter-gpu-manager-4-cuda13rather than legacydatacenter-gpu-manager. - Override the container platform only if you know why:
BEE_BUILDER_PLATFORM=linux/amd64 sh iso/builder/build-in-container.sh
- The shipped ISO is still
amd64. - Output ISO artifacts are written under
dist/.
