Or it could mean that dhclient hook merely asks systemd to restart ntpd service.

What it cannot stop is DHCP server providing "ntp-server" option anyway. ISC dhclient simply lacks the option to ignore certain options in DHCP reply.

Changing the contents of /etc/dhcp/dhclient-exit-hooks.d/ntp would make it more friendly for the purpose of the future updates. Reco
