Disable suspend and hibernation

In some cases if you are running this remotely on a vps you may not want to have the machine go to sleep so you can disable this with.

systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

or you can create a systemd config file /etc/systemd/sleep.conf.d/nosuspend.conf

[Sleep]
AllowSuspend=no
AllowHibernation=no
AllowSuspendThenHibernate=no
AllowHybridSleep=no
