 ### Don't reinvent the wheel
 
 This hardening project doesn't intend to reinvent the configuration stack for services. Aim to use official configuration projects first and provide hardening as a layer on top. The goal is remove the need for a user to configure all aspects of services and maintain security configuration. This way, the user can still configure a service using the interface provided by the official project.

+### hidepid on RHEL/CentOS 7
+
+When having `polkit-0.112-18.el7` (and later) installed and `/proc` mounted with `hidepid=2`, everytime someone uses `systemctl` the following error is displayed, but systemctl runs successfully.
+
+```
+Error registering authentication agent: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: Cannot determine user of subject (polkit-error-quark, 0)
+```
+
+We decided to set `hidepid=0` to remove the error message, if you want to use the other proposed workaround, you have to setup the user yourself and set our option to `hidepid_option: 2` via Ansible vars.
