A very opinionated (technically only for me) configuration that allows easy adding and removing of systems alongside custom configurations for each system.

Usage

This flake is intended to be used as an input to your own NixOS configuration:

dashNix = {
  url = "github:DashieTM/DashNix";
  inputs = {
    # ensure these are here to update the packages on your own
    nixpkgs.follows = "nixpkgs";
    stable.follows = "stable";
  };
};

You can then configure your systems in your flake outputs with a provided library command:

nixosConfigurations = inputs.dashNix.dashNixLib.build_systems { root = ./.; };

This command will build each system that is placed within the hosts/ directory. In this directory create one directory for each system you want to configure with DashNix. This will automatically pick up the hostname for the system and look for 3 different files that are explained below. (Optionally, you can also change the parameter root (./.) to define a different starting directory than hosts/)

In order for your configuration to work, you are required to at least provide a single config file with a further config file being optional for custom configuration. The hardware.nix specifies additional NixOS configuration, while home.nix specifies additional home-manager configuration. (both optional)

|- flake.nix
|- flake.lock
|- hosts/
|--- system1/
|------ configuration.nix (required)
|------ hardware.nix (optional)
|------ home.nix (optional)
|--- system2/

|------ hardware.nix (optional)
|------ home.nix (optional)
|--- system3/
|------ configuration.nix (required)
|------ hardware.nix (optional)
|------ home.nix (optional)

Here is a minimal required configuration.nix (the TODOs mention a required change):

{config, ...}: {
  # variables for system
  # TODO important changes
  conf = {
    # change this to your monitor and your pc name
    # should be something like DP-1
    defaultMonitor = "YOURMONITOR";
    # width x height  @ refreshrate
    defaultMonitorMode = "1920x1080@60";
    # scale for your main monitor
    defaultMonitorScale = "1";
    # your username
    username = "YOURNAME";
    # TODO only needed when you use intel -> amd is default
    # cpu = "intel";
    locale = "something.UTF-8";
    timezone = "CONTINENT/CITY";
  };
  # modules
  mods = {
    # default disk config has root home boot and swap partition, overwrite if you want something different
    drives = {
        # default assumes ROOT, BOOT, HOME and SWAP labaled drives exist
        # for an example without HOME see below
        # defaultDrives.enable = false;
        # extraDrives = [
        #   {
        #     name = "boot";
        #     drive = {
        #       device = "/dev/disk/by-label/BOOT";
        #       fsType = "vfat";
        #       options = [ "rw" "fmask=0022" "dmask=0022" "noatime" ];
        #     };
        #   }
        #   {
        #     name = "";
        #     drive = {
        #       device = "/dev/disk/by-label/ROOT";
        #       fsType = "ext4";
        #       options = [ "noatime" "nodiratime" "discard" ];
        #     };
        #   }
        # ];
    };
    sops.enable = false;
    nextcloud.enable = false;
    # default hyprland monitor config -> uncomment when necessary
    # TODO: Add more monitors when needed
    #   hyprland.monitor = [
    #     # default
    #     "${config.conf.defaultMonitor},${config.conf.defaultMonitorMode},0x0,${config.conf.defaultMonitorScale}"
    #     # second example monitor
    #     "DP-2,3440x1440@180,auto,1"
    #     # all others
    #     ",highrr,auto,1"
    #   ];
    # or amd, whatever you have
    gpu.nvidia.enable = true;
    kde_connect.enable = true;
    # login manager:
    # default is greetd
    # greetd = { };
    # sddm = { };
    # gdm = { };
  };
}

Nixos and Home-manager Modules

You can add additional modules or remove all of them by overriding parameters to the build_systems command:

nixosConfigurations =
    let
        additionalMods = {
            nixos = [
            # your modules
            ]; home = [
            # your modules
            ];
        }
        # passing this parameter will override the existing modules
        mods = {
            nixos = [];
            home = [];
        }
    in
    inputs.dashNix.dashNixLib.build_systems { root = ./.; inherit mods additionalMods; };

Additional Inputs

Just like modules, you can add additional inputs to your configuration.

nixosConfigurations =
    let
        additionalInputs = {
            something.url = "yoururl"
        }
    in
    inputs.dashNix.dashNixLib.build_systems { root = ./.; inherit additionalInputs; };

Stable/Unstable

Sometimes you want to differentiate between systems that are stable and unstable, e.g. for servers and desktops/laptops. This can be done with the overridePkgs flag for the lib function:

 nixosConfigurations =
   inputs.dashNix.dashNixLib.build_systems {
     root = ./stable;
     inherit additionalInputs;
     overridePkgs = true;
   }
   // inputs.dashNix.dashNixLib.build_systems {
     root = ./unstable;
     inherit additionalInputs;
   };

You can now place your systems in the respective directories. Keep in mind that the hosts directory will still need to exist in each variant. E.g. stable/hosts/yourserver and unstable/hosts/yourdesktop

Installation

You can find a custom ISO on my NextCloud server: Link. With this, you will receive the example config in /iso/example alongside the gnome desktop environment, as well as a few tools like gnome-disks, neovim, vscodium, a browser etc.

Alternatively, you can use whatever NixOS installer and just install your config from there, just make sure to set the drive configuration before.

Modules

This configuration features several modules that can be used as preconfigured "recipies". These modules attempt to combine the home-manager and nixos packages/options to one single configuration file for each new system. For package lists, please check the individual modules, as the lists can be long.
