NixOS Configuration with Flakes

This repository contains the configuration files for a NixOS system using Flakes. It provides a fully declarative system configuration for a Cinnamon-based desktop environment with essential tools, development utilities, and virtual machine support.

Features

• Flake-Based Configuration: Ensures reproducible system builds.
• Cinnamon Desktop Environment: Lightweight and user-friendly.
• Essential Tools: Includes utilities, browsers, and development tools.
• VM Integration: Clipboard sharing via spice-vdagent.

Note: Get ssh first!

• sudo nano /etc/nixos/configuration.nix
• Un-# services.openssh.enable = true;
• sudo nixos-rebuild switch --flake /etc/nixos#nixosvm

Files

1. flake.nix

The entry point for the NixOS flake. It defines:

• The nixpkgs input.
• The outputs section that points to the configuration.nix file.
• System architecture (x86_64-linux).

2. configuration.nix

The main system configuration file. It includes:

• Flakes Enablement: Allows nix-command and flakes features.
• Display and Desktop: Configures X11, LightDM, and Cinnamon.
• Networking: Uses NetworkManager for network management.
• Package Management: Declares system-wide packages, including:
  • Basic tools: git, curl, wget, htop
  • Browsers: firefox, brave
  • Development: python3, gcc, cmake
  • Utilities: vlc, neofetch, spice-vdagent
• User Management: Adds a user (pi) with passwordless sudo.
