See this change:
 http://svnweb.mageia.org/packages?view=revision&revision=272730
where I adapted our ntp package for this change.

Basically, ntpd (or chrony) itself is still started as normal (e.g.
enabled to start on boot). The ntp-units.d/ folder is just a high level
method to find the "right" ntp implementation when needed (i.e. it's not
run or looked at on every boot).

To explain further, if you do not have ntp enabled and you open the
gnome time preferences it should report that "Network Time" is disabled.
Enabling it will use systemd-timedated which will look for the right ntp
unit to enable via the ntp-units.d folder's *.list files. When it finds
an appropriate unit, it will first enable the service and then start it.
As it's been enabled, it will then start automatically on next boot.

So the *.list files is really just a hint to the higher level "enabling"
feature.

Hope this helps explain things a bit (and I hope my understanding of it
is correct too!)
