# Aider chat conversation:

USER: I ran this command:

 nixos-rebuild build-vm --flake ./#athame

And got this output:

building the system configuration...

       error: attribute 'hostname' missing

       at /nix/store/ds44l4g1yz0dd3ssqhlpv4r6wwh8p6r0-source/nixos/configuration.nix:77:25:

           76|   # TODO: Set your hostname
           77|   networking.hostName = inputs.hostname;

ASSISTANT: The error message indicates that the attribute 'hostname' is missing. This is likely because the `inputs` in `nixos/configuration.nix` does not contain a `hostname` attribute.

The `hostname` attribute is defined in `flake.nix` under `nixosConfigurations` for each system (like `athame` and `metatron`). However, this `hostname` attribute is not being passed to `nixos/configuration.nix`.

To fix this, we need to modify `nixos/configuration.nix` to accept `hostname` as an argument.

Here is the *SEARCH/REPLACE* block:

nixos/configuration.nix
```nix
<<<<<<< SEARCH
{
  inputs,
  outputs,
  lib,
  config,
  pkgs,
  ...
}: {
=======
{ inputs, outputs, lib, config, pkgs, hostname, ... }: {
>>>>>>> REPLACE
```

This change will allow `nixos/configuration.nix` to accept `hostname` as an argument. Now, when you run the command `nixos-rebuild build-vm --flake ./#athame`, the `hostname` attribute from `flake.nix` will be passed to `nixos/configuration.nix`, and the error should be resolved.
