Stephen Bolton's Dotfiles

Nix flake-based dotfiles using snowfall-lib for module organization.

Structure

• systems/<arch>-<platform>/<hostname>/ - NixOS and darwin system configurations
• homes/<arch>-<platform>/<user>@<hostname>/ - Home Manager configurations
• modules/<context>/<name>/ - Reusable modules
• packages/<name>/ - Custom packages
• overlays/<name>/ - Nixpkgs overlays

Building Systems

# Build NixOS system
nixos-rebuild switch --flake .#<hostname>

# Build darwin system
darwin-rebuild switch --flake .#<hostname>

# Build home configuration
home-manager switch --flake .#<user>@<hostname>

Creating a New Host

1. Create directory: systems/<arch>-<platform>/<hostname>/
2. Copy hardware config from installer to ./hardware-configuration.nix
3. Create default.nix:

{ lib, inputs, ... }:
{
  imports = [
    ./hardware-configuration.nix
  ];

  networking.hostName = "<hostname>";
}

Creating a New Home

1. Create directory: homes/<arch>-<platform>/<user>@<hostname>/
2. Create default.nix with home configuration

ISO Generation

If new host needs access to secrets, update the comment in systems/x86_64-install-iso/minimal/default.nix with the age key.

Don't commit the secret dummy

Build the installer ISO:

nix build '.#install-isoConfigurations.minimal'

Perform traditional Nixos installation. If secrets are needed, copy the /etc/orlando-age-key.txt into the new user's ~/.config/sops/age-key.txt.
