# 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.
