This is a stupid-simple client for my Netlify DDNS "bouncer" here:
The files here should be simple and self-explanatory enough with the context from the other repository.
sudo make install
The first time you run this, example.env will be copied to .env and
opened in your editor so you may set your endpoint and credentials.
After that, .env is again copied to /etc/netlify-ddns-client/rc and the
systemd service and timer will be installed and started.
sudo make uninstall
