I'm not sure that I parse your English properly. Could you be more
explict, preferably in a code review of
http://gerrit.ovirt.org/#/c/11291/ ?
I guess this will work, however this is primitive approach that a service should
explicitly state the service provider in multi-option configuration.
Let's assume there is yet another alternative to ntpd, then all services should have
three alternatives...
And what if I add my own alternative to my system? then I need to manually fix all
services... as the authors of these were not aware of the new service I introduce.
It is systemd I don't like...
