I agree it would be useful to have that field, I'll add it in the next release.
Running it with systemd is pretty straightforward, simply download the binary or compile it yourself (give it execution permissions) and create the following service with sudo nano /etc/systemd/system/acceptlnd.service
sudo nano /etc/systemd/system/acceptlnd.service
sudo systemctl enable acceptlnd
andsudo systemctl start acceptlnd
.
