once you have values set through the D-Bus API they have priority and
that is the only possible choice. The provided configuration options in
hcid.conf are only default values for the distributions. No user should
ever modify these values. This also means that YaST should no longer
modify hcid.conf. Simply call the appropriate method via dbus-send.

In general you can have as many configuration tools as you want. The
only small thing you need to take care of is to listen to signals for
your settings, because another tool might change a value while you are
running.
