2.3. MODIFYING CONTROL GROUPS
Each persistent unit supervised by systemd has a unit configuration file in the /usr/lib/systemd/system/ directory. To change parameters of a service unit, modify this configuration file. This can be done either manually or from the command-line interface by using the systemctl set-property command.
2.3.1. Setting Parameters from the Command-Line Interface
The systemctl set-property command allows you to persistently change resource control settings during the application runtime. To do so, use the following syntax as root:
~]# systemctl set-property name parameter=value
Replace name with the name of the systemd unit you wish to modify, parameter with a name of the parameter to be changed, and value with a new value you want to assign to this parameter.
Not all unit parameters can be changed at runtime, but most of those related to resource co
