NixOS System Configurations

My personal NixOS configuration, packaged as a flake for reproducible system and user (home-manager) configuration across machines.

Flake Structure

.
├── assets             # Assets
├── hosts              # Per-host NixOS configurations
├── lib                # Utility functions
├── modules            # Reusable modules
│   ├── home-manager   # Home Manager configurations
│   └── nixos          # NixOS configurations
└── overlays           # Package Overlays

This flake uses import-tree to recursively import all modules, overlays and hosts. Most modules are enabled by default for all hosts. Optional modules use Option Declarations for per-host configuration.

Imperative Setup

While most of the system configuration is declarative, some state is intentionally managed outside of Nix and must be configured manually after installation.

• User Passwords: Set a password for your user account with passwd <username>.
• Network Connections: Configure Wi-Fi and import VPN profiles using NetworkManager (nmcli or a graphical frontend).
• GitHub Access Token: Optionally add a GitHub API token to ~/.config/nix/nix.conf to avoid rate limiting.
• Bluetooth Devices: Pair Bluetooth devices using bluetoothctl.
