Ryan Yin 2c7629000f refactor: rename the three VM hosts to 12kingdoms-*
Drop the now-meaningless kubevirt- prefix and move the hosts out of
hosts/k8s/, following the existing 12kingdoms-shoukei layout: the
directory and output carry the theme prefix while the configuration,
hostname and colmena target are the bare name (shoryu, shushou, youko).

- hosts/k8s/kubevirt-* -> hosts/12kingdoms-*; the shared disko config
  becomes host-disko-fs.nix; the now-different relative imports are fixed
- outputs, vars/networking.nix keys, the Justfile recipes/tags, the eval
  tests and the docs follow
- colmena reaches these hosts by IP (a new targetHost override), since
  their DNS name changes with the hostname and is not resolvable until
  the router learns it

Library

This directory contains helper functions used by flake.nix to reduce code duplication and make it easier to add new machines.

Current Functions

Core System Generators

  1. attrs.nix - Attribute set manipulation utilities
  2. macosSystem.nix - macOS configuration generator for nix-darwin
  3. nixosSystem.nix - NixOS configuration generator
  4. colmenaSystem.nix - Remote deployment configuration for colmena

Specialized Module Generators

  1. genK3sAgentModule.nix - K3s agent node configuration generator
  2. genK3sServerModule.nix - K3s server node configuration generator
  3. genKubeVirtGuestModule.nix - KubeVirt guest VM configuration generator
  4. genKubeVirtHostModule.nix - KubeVirt host configuration generator

Entry Point

  1. default.nix - Main entry point that imports all functions and exports them as a single attribute set

Usage

These functions are designed to:

  • Generate consistent configurations across different architectures
  • Provide type-safe configuration for complex systems
  • Enable easy scaling of the infrastructure
  • Support both local development and production deployments

Architecture Support

  • x86_64-linux: Primary desktop systems
  • aarch64-linux: ARM64 Linux systems (Apple Silicon, SBCs)
  • aarch64-darwin: Apple Silicon macOS systems
