Found by running the unattended install in an offline QEMU VM: - compgen is missing from nixpkgs' non-interactive bash (the package shebang) — replaced with plain glob tests in hardware-db and prewipe - disko's eval resolves <nixpkgs> via NIX_PATH (a dead channel on the ISO) and tried channels.nixos.org — export NIX_PATH to the pinned nixpkgs source and point the flake registry at an empty baked file - lock nomarchy by path (the source the ISO carries) instead of git+https: git inputs clone even when narHash is known, which kills offline installs; `original` keeps the forge URL so a later `nix flake update` re-resolves normally. Works from dirty-tree ISOs too. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
