Apologies for the delay in responding. Your mail got filtered to a
folder that I don't check frequently. I only just saw your mail while
preparing a new upload.

I've just uploaded a new version 4.0 to unstable. The instructions to
enable systemd services were out of date - the new upload updates
these.

Quoting from the README -

｜ 2. Systemd services
｜ 
｜ linuxptp package ships with service templates for ptp4l and
｜ phc2sys. The services need to be instantiated for the required network
｜ interface.
｜ 
｜ For instance, to instantiate ptp4l service for eth2,
｜ 
｜ $ systemctl enable ptp4l@eth2
｜ $ systemctl enable ptp4l@eth2
｜ 
｜ Replace 'eth2' with the actual network interface.
｜ 
｜ The service phc2sys syncs the system clock with the PTP clock. It is not
｜ enabled and started by default. To activate this service, invoke the
｜ following commands as root:
｜ 
｜ $ systemctl enable phc2sys@<interface>
｜ $ systemctl start phc2sys@<interface>
｜ 
｜ Replace '<interface>' with the actual port, e.g., eth2.

Hope this helps.
