systemd_networkd

Set up systemd-networkd. For single NIC static IP setup, specify the static IP address, gateway address, and DNS server address. For advanced setup, it will copy all configuration files inside the {{ networkd_configs_dir }} to /etc/systemd/network. The configuration file will have permission 640 with owner root and group systemd-network. This is for preventing the leaking of private keys when setting up WireGuard using systemd-networkd.
