Nix Configuration Improvements

This PR contains improvements and suggestions for the nix-config repository based on a comprehensive analysis.

Changes Made

1. Fixed Inconsistent stateVersion ✅

  • Issue: The VPN host was using stateVersion = "23.05" while all other hosts use "24.05"
  • Fix: Updated VPN to use "24.05" for consistency across all hosts
  • Importance: State version consistency ensures all hosts use compatible NixOS modules

Additional Suggestions Documented

I've created an IMPROVEMENTS.md file with comprehensive suggestions for future improvements including:

2. Flake.nix Improvements

  • Consider adding llama-cpp and nixos-mailserver to outputs declaration
  • Add home-manager input when ready to use it

3. Duplicate Module Imports

  • Remove duplicate sops-nix import in hosts/common/global/default.nix

4. Missing Firewall Rules

  • VPN host's NAT configuration may need additional rules for proper routing

5. Documentation

  • Add README with build/rebuild instructions
  • Document host purposes and secret management setup

6. Security Improvements

  • Enable ACME defaults for Let's Encrypt
  • Add rate limiting to public-facing services
  • Implement fail2ban more consistently

7. Performance Optimizations

  • Review kernel parameters per host type
  • Consider ZFS compression where appropriate

8. Maintenance

  • Regular flake.lock updates
  • Remove old commented-out configurations

Files Changed

  • hosts/vpn/default.nix - Fixed stateVersion
  • IMPROVEMENTS.md - New documentation file with all suggestions

Testing

This change maintains the same stateVersion (24.05) as requested and should not affect existing functionality. The VPN host will now be consistent with all other hosts.

Build Commands

# Build and test the changes
nix flake check

# Test VPN host specifically
nixos-rebuild switch --flake .#vpn
