In the latter case the user will miss any changes by the
developers/packager to the service file.
I was looking for the compromise: small change to the service file
making a copy in /etc/systemd/system unnecessary.

I must look into this way of solving things as it did not work for me yet.
I installed the default ntpd.service file.
Then in  /etc/systemd/system/ntpd.service.d/ I created
10-environment.conf with contents:
ExecStart=/usr/sbin/ntpd -u ntp:ntp $OPTIONS

/etc/sysconfig/ntpd contains:
# Command line options for ntpd

But it appears that these suggestions are not used (despite reload of
systemd) as the -N option is still passed to ntpd.
