Reboot names a function, with lambda list (&REST WORDS):
Restart the game server.
No, really; this actually kills the game server with an error exit so that it will (hopefully) be restarted by SystemD.
This is a violent way to go, and is for emergencies only.
#reboot
#reboot
The server will quit with Unix exit status 66 in 3 seconds after the command is received.
