mchusandClaude Sonnet 5 bbc6fb1c36 fix(nvidia): own /var/log/nvidia-dcgm so dcgmi diag deployment check passes
nv-hostengine drops privileges to --service-account nvidia-dcgm for all
file I/O and writes diagnostics to DCGM_HOME_DIR (/var/log/nvidia-dcgm,
per the packaged unit's Environment=). The package postinst doesn't
reliably create/own this directory inside a live-build chroot, so
dcgmi diag's software deployment check fails with
DCGM_FR_FILE_CREATE_PERMISSIONS at boot even though every GPU passes
the actual hardware tests.

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-boot toram, 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.
  • The NVIDIA variants ship the root filesystem as several semantic SquashFS layers (live/filesystem-v<ver>-NN-*.squashfs) plus an explicit live/filesystem.module that fixes their OverlayFS order. This bounds the data a toram retry must re-read after a virtual-media drop; it is not a fix for virtual-media instability. amd / nogpu keep a single squashfs. See bible-local/architecture/squashfs-layers.md.
  • The builder splits the layers deterministically after the full lb build, verifies each one, re-merges them into a bootable rootfs, and only then deletes the monolith. The fast path is disabled for a multi-layer medium (it forces a full build).
  • Target systems require at least 16 GB of installed RAM for the full compressed live medium plus normal runtime overhead. On supported hardware, do not classify a mid-copy failure as low RAM without direct ENOSPC, OOM, or tmpfs-limit evidence.
  • The NVIDIA variant installs DCGM 4 packages matched to the CUDA user-mode driver major version. For driver branch 580 / CUDA 13.x, the package family is datacenter-gpu-manager-4-cuda13 rather than legacy datacenter-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/.
