# NixOS Configuration Files wit Flakes, Home-Manager
## Description
My NixOS configuration repository

## Install a new host 
1. Install NixOS with graphical ISO image (e.g. GNOME). During the installation the desktop environment can be choosen.
2. Reboot into NixOS
3. Edit `/etc/nixos/configuration.nix` with sudoedit
    a) Change hostname
    b) Enable flakes. Add the following lines:
```
# Enable flakes
 nix.settings.experimental-features = [ "nix-command" "flakes" ];
```
    c) Install tmux, neovim, git by adding them to `environment.systemPackages = with pkgs; [`
4. Apply changes: `sudo nixos-rebuild switch` and reboot
5. Clone NixOS config repository to /home/$USER/nixos:
```
cd
git clone https://git.plueschbit.de/jan/nixos-conf ~/nixos
```
6. Add the new host to repository
    a) Create ~/nixos/hosts/$HOSTNAME
    b) `cp /etc/nixos/*.nix $HOSTNAME/.`
    c) Edit `~/nixos/flake.nix` and add section for new host
    d) Stage new config files: `git add flake.nix hosts/$HOSTNAME/*`. Otherwise, nixos-rebuild will refuse to work with the files.
8. Apply config: `sudo nixos-rebuild switch --flake ~/nixos/#<host>`
