Title:
systemd starts two copies of ntp at boot time
Status in ntp package in Ubuntu:
Expired
Bug description:
My system monitoring check noticed a stale /var/run/ntpd.pid pidfile
on a xenial machine that rebooted at 2 AM after unattended upgrades.
ntpd itself was running, but with a different pid.
Digging through journalctl I can see

As you can see, for some reason systemd starts ntpd twice, so there's
a race to take over the socket, and a race to take over the pidfile.
ntpd[773] gets the socket, ntpd[780] gets the pidfile.
