Description

Diagnostic:

After intall, policy generation (top right) is red. When clicking on details, you can see:

⇨  Exit code=1 for hook: '/opt/rudder/etc/hooks.d/policy-generation-finished/50-reload-policy-file-server'.
 stdout: 
 stderr: 'rudder-cf-serverd.service is not active, cannot reload.
'

If you try to start that service by hand (systemctl start rudder-cf-serverd.service), it fails and you can see in journald:

Dec 17 13:11:50 server setroubleshoot[21591]: SELinux is preventing /usr/lib/systemd/systemd from execute access on the file cf-serverd. For complete SE>
Dec 17 13:11:51 server platform-python[21591]: SELinux is preventing /usr/lib/systemd/systemd from execute access on the file cf-serverd.

                                               *****  Plugin catchall (100. confidence) suggests   **************************

                                               If you believe that systemd should be allowed execute access on the cf-serverd file by default.
                                               Then you should report this as a bug.
                                               You can generate a local policy module to allow this access.
                                               Do
                                               allow this access for now by executing:
                                               # ausearch -c '(-serverd)' --raw | audit2allow -M my-serverd
                                               # semodule -X 300 -i my-serverd.pp

WORKAROUND:

Disable selinux: setenforce 0
