nix-config/lib

Library

This directory contains helper functions used by outputs/default.nix (and the installer flake) to reduce code duplication and make it easier to add new machines.

Current Functions

Core System Generators

1. macosSystem.nix - macOS configuration generator for nix-darwin
2. nixosSystem.nix - NixOS configuration generator
3. colmenaSystem.nix - Remote deployment configuration for colmena

Specialized Module Generators

4. genK3sServerModule.nix - K3s server node configuration generator
5. genK3sAgentModule.nix - K3s agent/worker node configuration generator
6. genVmHostModule.nix - physical VM host (bridge + libvirt) configuration generator
7. genMicrovmGuestModule.nix - NixOS microVM guest configuration generator
8. genLibvirtDomainXml.nix - libvirt domain XML generator (imported directly by host configs)

Shared Presets

9. systemdHardening.nix - systemd sandboxing preset for exposed services

Entry Point

10. default.nix - Main entry point that imports the generators and exports them as a single attribute set, plus the relativeToRoot and scanPaths helpers

Usage

The generators import the shared host modules, so a new machine supplies its own values and system-specific attributes. colmenaSystem covers remote deployment, and genLibvirtDomainXml renders the domain XML for one guest.
