Secrets Management

All secrets are encrypted with sops-nix and Age encryption:

• Encrypted at rest in version control
• Runtime decryption by NixOS
• Fine-grained permissions per service

See Secrets Management Guide for details.

Adding a New Machine

1. Update flake.nix

nixosConfigurations = {
  newmachine = mkNixosConfiguration "newmachine" "newuser";
};

homeConfigurations = {
  "newuser@newmachine" = mkHomeConfiguration "x86_64-linux" "newuser" "newmachine";
};

2. Create host configuration

mkdir -p hosts/newmachine
sudo nixos-generate-config --show-hardware-config > hosts/newmachine/hardware-configuration.nix

3. Create home configuration

mkdir -p home/newuser/newmachine

4. Deploy

git add .
just nixos-rebuild
just home-manager-switch

Customization

Add Packages

NixOS system packages:

# modules/nixos/common/default.nix
environment.systemPackages = with pkgs; [
  your-package
];

User packages:

# modules/home-manager/common/default.nix
home.packages = with pkgs; [
  your-package
];

Troubleshooting

Build Failures

# Validate configuration
just flake-check

# Show detailed error trace
nixos-rebuild switch --show-trace

Home Manager Issues

# Check home-manager logs
journalctl --user -u home-manager-${USER}.service

# Rebuild with verbose output
home-manager switch --show-trace
