Michael Chus f5d175f488 Fix toram: patch live-boot to not use O_DIRECT when replacing loop to tmpfs
losetup --replace --direct-io=on fails with EINVAL when the target file
is on tmpfs (/dev/shm), because tmpfs does not support O_DIRECT.
Strip the --direct-io flag from the replace call and downgrade the
verification failure to a warning so boot continues.

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

Rebuild the builder image:

sh iso/builder/build-in-container.sh --rebuild-image

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.
  • 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 / 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/.
