Vinetos Nix* Configurations

This repository contains all my configurations for all my nix-based systems. It includes NixOS systems configurations, Nix configurations and nix-darwin configurations with per-user configurations, and per-host configurations. This repository is built on top of Nix Flakes and nixos-unified.

This config allow me to have per-machine configuration (e.g. modules, hardware specific) AND per-user per-machine configuration (e.g. profiles, workspaces, ...).

I use this repository to manage my personal computers, servers, and workstations including :

• Laptops with NixOS and MacOS + Nix-Darwin
• Desktop with NixOS
• WSL2 with NixOS and Ubuntu
• Servers with NixOS and Debian + Nix
• Raspberry Pi with NixOS

What's inside

Some of the noticeable things I use :

• Nix with Flakes built on top of latest stable channel + easy unstable access
• Nixos-unified (flake-parts module) to provide a consistent interface for all my configurations
• Home-manager for per-user configuration
• Wayland (Hyprland, Hyprpaper, ...)
• DoAs (alternative to sudo)
• Kitty terminal, Fish as shell

Architecture

Start from flake.nix (see Flakes). flake-parts is used as the module system.

Directory layout

Tip

This repo use autowiring of flake outputs based on this directory structure.

Path	Corresponding flake output
./configurations/{nixos,darwin,home}/foo/	{nixos,darwin,home}Configurations.foo
./mdules/{nixos,darwin,home,flake-parts}/foo/	{nixos,darwin,home,flake}Modules.foo
./overlays/foo.nix	overlays.foo
./packages/bar	``

How to use

• To add a new host, install it with NixOS Installer or Nix-Darwin, then

  • Create a new directory in configurations/{nixos/darwin/home}/hostname depending on underlying OS.
  • Create or move home-manager configurations to configuration/home/my-user.nix
  • Copy the generated configuration.nix and hardware-configuration.nix to the new directory and create the default.nix.
  • Apply the configuration with nix run

• To apply the configuration, run nix run

  • You are no required to run it as root, it will ask for sudo password when needed

    nix run # Will update the configuration based on the hostname
    # Or, `nix run .#<computer>`

• To update NixOS (and other inputs) run nix flake update

  • You may also update a subset of inputs, e.g.

    nix flake lock --update-input nixpkgs --update-input darwin --update-input home-manager
    # Or, `nix run .#update`

• To free up disk space,

  sudo nix-env -p /nix/var/nix/profiles/system --delete-generations +2
  sudo nixos-rebuild boot

• To autoformat the project tree using nixpkgs-fmt, run nix fmt.

• To build all flake outputs (locally or in CI), run nix --accept-flake-config run github:juspay/omnix ci build
