NixOS Homelab Configuration

A comprehensive NixOS configuration for managing my homelab infrastructure with smart home, media, monitoring, and DNS management services.

• ZFS Storage: ser8 uses ZFS with automatic snapshots and weekly scrubs
• Impermanence: Root filesystem rollback on boot for stateless operation
• Tailscale VPN Integration: Uses caddy with tailscale plugin for convenient MagicDNS service access
• Monitoring: Prometheus + Grafana for comprehensive metrics
• Secrets Management: SOPS with age encryption for sensitive data
• Multi-Architecture: Supports x86_64 and ARM (Raspberry Pi)

This was my first experience with NixOS. This repo will eventually be migrated to use:

• https://github.com/Doc-Steve/dendritic-design-with-flake-parts
• https://github.com/mightyiam/dendritic

Infrastructure Overview
