Age of Insanity

A) Setup autorun script: Put autorun_gameprod.sh in /home/aoi/
B) Setup autorun script to autorun:  Put autorun_gameprod.service in /etc/systemd/system/autorun_gameprod.service
C) Reload systemd and start the service
sudo systemctl daemon-reload
sudo systemctl enable --now autorun_gameprod.service
D)  Verify it stays up
sudo systemctl status autorun_gameprod.service
sudo journalctl -fu autorun_gameprod.service
E) Should just run now automatically upon boot up.
F) That said, to troubleshoot, or for reference:
To run AOI's autorun script: ./autorun &
To stop AOI's autorun script:  touch a file called .killscript in the same directory, which will stop the script the next time it autostarts the MUD.
To run AOI just one time:  ./test &
