For example, if the settings in /etc/cgconfig.conf are looking like this:
The statement CPUQuota=40% sets the cpu quota to 40% (cfs_quota_us divided by cf_period_us multiplied by 100). The program can then be started by running systemctl start example.service.
If a program already has a service file, instead of editing the existing one drop-ins can be used for additional settings such as quotas. For drop-ins, a subdirectory for the service needs to be created, for example /etc/systemd/system/example.service.d/, and a files with names ending on .conf, for example 10-resource-control.conf can be created in it to set the additional directives for the service. Implementing above settings, /etc/systemd/system/example.service.d/10-resource-control.conf would look simply like this:
