fix(installer): refresh embedded runbook (Addison)#4903
Merged
Conversation
…are-config copy step The runbook baked onto the ISO at /etc/zeta-install.md was authored before the per-host configs landed (PR #4898 stack), so it still said "Today: installer only; per-host configs land in follow-up PRs." Those configs have been on main since 02:53:15Z — the runbook just hadn't been updated to match. Changes to the embedded text: - Step 6 now shows the cp command that moves hardware-configuration.nix from where nixos-generate-config writes it (/mnt/etc/nixos/) into the per-host directory the flake actually reads (/mnt/etc/zeta/infra/ nixos/hosts/<host>/). Without this step, nixos-install builds against the placeholder hardware-configuration.nix shipped in the repo and the target boots with wrong fileSystems/kernel modules. - Step 7 now enumerates the actual nixosConfigurations on main: installer, control-plane, worker-gpu-01, worker-gpu-02. Marks `installer` as not-for-target-install so a future user doesn't pick it by accident. Cosmetic-only fix; no code change. Surfaces the right install workflow for the first real cluster bootstrap from this ISO. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Pull request overview
Updates the NixOS installer ISO’s embedded offline runbook (/etc/zeta-install.md) so it matches the current flake layout with per-host NixOS configurations and avoids accidentally installing with placeholder hardware configuration.
Changes:
- Step 6 now instructs copying the generated
hardware-configuration.nixinto the selected per-host directory underinfra/nixos/hosts/<host>/. - Step 7 now lists the current
flake.nixnixosConfigurationshostnames and clarifiesinstalleris ISO-only (not a target install).

Summary
The runbook baked onto the USB at `/etc/zeta-install.md` was authored before per-host configs landed and still said "Today: installer only; per-host configs land in follow-up PRs". Those per-host configs (control-plane, worker-gpu-01, worker-gpu-02) are on main now — the runbook just hadn't caught up.
