Nix Setup

My personal Nix flake for NixOS with standalone Home Manager for non-NixOS systems.

Note: This uses Colemak-DH-ISO keyboard layout by default. Edit keyboard.nix and niri.kdl before installing.

Important

Uses ~/dev/nix path (install script default).

Install

Current install script works on both NixOS and Fedora with standalone Home Manager.

NixOS: Clones repo to ~/dev/nix, then applies NixOS configuration.

Fedora: Clones repo, applies system settings, installs system dependencies, installs Nix, and applies Home Manager configuration.

curl -fsSL jaycem.dev/nix | bash

Nix Cli Helper

The ns cli is included as a pkg derivation and provides an unified and easier interface for managing NixOS and Home Manager flake based configurations with the same cli.

ns <action> [target] [options]

When no target is specified, both NixOS and Home Manager are applied. The update action also rebuilds after updating the flake.

Available actions: update, switch, clean, news

Available targets: home, nixos

Available options: -c, --config <dir>, --user <name> (home-manager profile), --host <name> (nixos profile), --gc (garbage collection)

Run ns -h for more information.

Examples

ns switch                       # Rebuild both NixOS and Home Manager
ns switch home                  # Rebuild Home Manager only
ns switch nixos --host laptop   # Rebuild NixOS with laptop profile
ns switch home --user jay       # Rebuild Home Manager with jay profile
ns update --gc                  # Update and run garbage collection

Project Structure

This flake provides a unified configuration system that works on both NixOS and non-NixOS systems.
