mchusandClaude Opus 4.8 95d3532bb9 build(iso): unify GRUB/isolinux boot menus, add iommu=pt to fail-safe

The GRUB and isolinux menus (and their two sources of truth — the staged
templates and build.sh's write_canonical_* generators that rewrite the built
menu) had drifted: GRUB shipped a lean set, isolinux carried extra
display-debug entries (gsp-off, kms, kms-gsp-off) and lacked a WIPE entry in
the canonical writer. Collapse all four to one set:

  normal, load-to-RAM (default), no-GUI/troubleshooting (gsp-off, pci=realloc),
  fail-safe, WIPE ALL DISKS, Memory Test, + UEFI Firmware Settings (EFI only)

The fail-safe entry gains iommu=pt (AMD-Vi passthrough) — the OS-side half of
the vendor fix for the MSI CG480-S6053 cross-socket nvbandwidth reboot; ACS
can't be toggled from a stock-kernel cmdline so that stays a BIOS setting.
default stays index 1 = toram (config.cfg set default=1).

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.
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 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/.
