Edit with systemctl edit to add restart on fail to a service – nfs-ganesha

A quick tip how to edit a service unit file under a c system like CentOS Stream 9 or Ubuntu. The best way is to edit it with the the tool “systemctl edit [service_name]”, which will trigger the default editor to open a temporary copy of the systemd unit file with the service name used with it. The default editor in the console is controlled by “EDITOR” variable and may be changed prior using the systemctl edit. After a successful manipulation of the system unit file the new one will be installed and a reload of the systemd unit files will be triggered with “systemctl daemon-reload” automatically. Indeed, it is just a text edit of a text file, which will do several actions when using “systemctl edit” command.
