Sometimes, on a SNO with DU profile the openshift_ptp_process_status metric is missing after the initial installation and configuration.

4.14.21
ptp-operator.v4.14.0-202404030309

    Not always, sporadic

    1. Deploy SNO with DU profile configuration
    2. Check ptp metrics for openshift_ptp_process_status

oc -n openshift-ptp exec ds/linuxptp-daemon -c linuxptp-daemon-container -- curl -s http://localhost:9091/metrics  | grep openshift_ptp_process_status     

No metric returned.    

# HELP openshift_ptp_process_status 0 = DOWN, 1 = UP
# TYPE openshift_ptp_process_status gauge
openshift_ptp_process_status{config="ptp4l.0.config",node="sno.kni-qe-67.lab.eng.rdu2.redhat.com",process="phc2sys"} 1
openshift_ptp_process_status{config="ptp4l.0.config",node="sno.kni-qe-67.lab.eng.rdu2.redhat.com",process="ptp4l"} 1

After deleting/re-creating the linuxptp-daemon pod the metric openshift_ptp_process_status shows up.
