Or if you want to install to your real root:
sudo make install
sd-networkd-wg-ddns (--interval/-i [interval]) [netdev name] ([netdev name] ([netdev name] ...))
--interval/-i [interval] set the interval between each check
[netdev name] netdev names under '/etc/systemd/network', without .netdev suffix
Example:
sd-networkd-wg-ddns --interval 1 30-wireguard-company 40-wiregard-personal
This means to read netdev configs /etc/systemd/network/30-wireguard-company.netdev and /etc/systemd/network/40-wireguard-personal.netdev, then watch for the network interfaces they defined, checking for any peers with an endpoint with a domain name as host. With a 1-second interval, compare the address on interface and the one resolved from domain, and update them should they differ.
Before using the systemd unit, configure its arguments in `/etc/conf.d/sd-networkd-wg-ddns:
SD_NETWORKD_WG_DDNS_ARGS="--interval 1 30-wireguard-company 40-wiregard-personal"
Then enable and start the bundled sd-networkd-wg-ddns.service:
sudo systemctl enable --now sd-networkd-wg-ddns.service
