Distro detection is done heuristically through the presence of a
`/nix/store` folder.
NixOS typically uses a script-based network configuration system that
isn't easy to configure from the outside, while the configuration
snippets would be simple to generate, bringing them in effect isn't.
LXC templates generated for proxmox are instead expected to use
systemd-networkd.
