PIDFile references a path below legacy directory /var/run/

Symptoms

SystemD reports a message about the PID file during cPanel restarts or cPanel updates.

systemd[1]: /etc/systemd/system/cpanel.service:10: PIDFile= 
references a path below legacy directory /var/run/, 
updating /var/run/cpsrvd.pid → /run/cpsrvd.pid; 
please update the unit file accordingly.

Description

cPanel services use the path "/var/run", but SystemD classifies this as a legacy path, as it was compatible with older systems. This message will appear often during restarts, but it doesn't cause any problems. The message can be safely ignored.

We've opened an internal case for our development team to investigate this further. For reference, the case number is CPANEL-47773. Follow this article to receive an email notification when a solution is published in the product. 

Workaround

This can be safely ignored. It doesn't cause any issues.
