Imo the message is very helpful, it is telling you you have dbus service
twice. Dbus service is part of %desktop-services and you've put that twice into
your config according to the snippet. So you have introduced two dbus
services. You need to use just one %desktop-services and modify that,
not use the same list twice. modify-services just takes a list and
returns a modified list, in the first case removing gdm from it,
in the second case modifying sysctl.
