Replace the single VPN container (veth pair, host-side auth scripts) with a
multi-container setup on a shared bridge network:
- Dedicated VPN container handles all PIA auth, WireGuard config, NAT, and
optional port forwarding DNAT
- Service containers default-route through VPN container (leak-proof by topology)
- Host runs tinyproxy on bridge for PIA API bootstrap before WG is up
- WG interface is still created in host netns and moved into VPN container
namespace
- Monthly renewal to ensure that connection stays up (PIA allows connections to
last up to 2 months)
- Drop OpenVPN support entirely
Gatus is configured entirely via YAML (mapped from Nix attrsets),
making nix-config the single source of truth for all monitoring
config instead of Uptime Kuma's web UI/SQLite database.
- Add incus.nix module for fully declarative Incus/LXC containers
- Build NixOS LXC images using nixpkgs.lib.nixosSystem
- Ephemeral containers: recreated on each start, cleaned up on stop
- Use flock to serialize concurrent container operations
- Deterministic MAC addresses via lib.mkMac to prevent ARP cache issues
- Add veth* to NetworkManager unmanaged interfaces
- Update CLAUDE.md with coding conventions and shared lib docs
