@Christian_Bolufer I believe you are referring to `sudo reboot` in the link above to the [pool school config files](https://forum.cardano.org/t/updating-stake-pool-school-config-files/37749/14). You just need to run that command in the cli to restart the server. You will be logged out, as the machine reboots and will have to log back in.
