# Aider chat conversation:
USER: I'm a bit concerned about setting the hostname in `nixos/configuration.nix` , as I want to use the same basic configuration for all of my devices
ASSISTANT: I understand your concern. You can use a variable for the hostname in `nixos/configuration.nix` and pass it in from the `flake.nix` file when defining the `nixosConfigurations`. This way, you can have the same default `nixos/configuration.nix` for every system and just change the hostname for each system in the `flake.nix` file.
Here are the *SEARCH/REPLACE* blocks:
flake.nix
```nix
<<<<<<< SEARCH
athame = nixpkgs.lib.nixosSystem {
specialArgs = {inherit inputs outputs;};
=======
athame = nixpkgs.lib.nixosSystem {
specialArgs = {inherit inputs outputs; hostname = "athame";};
>>>>>>> REPLACE
```
flake.nix
```nix
<<<<<<< SEARCH
metatron = nixpkgs.lib.nixosSystem {
specialArgs = {inherit inputs outputs;};
=======
metatron = nixpkgs.lib.nixosSystem {
specialArgs = {inherit inputs outputs; hostname = "metatron";};
>>>>>>> REPLACE
```
nixos/configuration.nix
```nix
<<<<<<< SEARCH
networking.hostName = "your-hostname";
=======
networking.hostName = inputs.hostname;
>>>>>>> REPLACE
```
This will replace the hardcoded hostname in `nixos/configuration.nix` with a reference to the hostname defined in the `flake.nix` file.
# Aider chat conversation:
USER: Let's create the kde-desktop.nix
ASSISTANT: Sure, let's create a new file `nixos/kde-desktop.nix` with a basic KDE desktop configuration.
Here is the *SEARCH/REPLACE* block:
nixos/kde-desktop.nix
```nix
<<<<<<< SEARCH
=======
{ config, pkgs, lib, ... }:
{
# Enable the KDE Desktop Environment.
services.xserver.displayManager.sddm.enable = true;
services.xserver.desktopManager.plasma5.enable = true;
# Define a user account. Don't forget to set a password with ‘passwd’.
users.users.jane = {
isNormalUser = true;
extraGroups = [ "wheel" ]; # Enable ‘sudo’ for the user.
};
# This value determines the NixOS release from which the default
# settings for stateful data, like file locations and database versions
# on your system were taken. It‘s perfectly fine and recommended to leave
# this value at the release version of the first install of this system.
# Before changing this value read the documentation for this option
# (e.g. man configuration.nix or on https://nixos.org/nixos/options.html).
system.stateVersion = "23.05"; # Did you read the comment?
}
>>>>>>> REPLACE
```
This is a basic KDE desktop configuration. You can customize it according to your needs.
