As I'm told that making bluez autodetect that is difficult... Will take route b) 
then and split out the config files into a bluez4-config package. Would it be ok 
to make that package depend on the machine? First I wanted to do an extra 
package (something like a machine dependent bluez4-config-shr), but maybe it is 
of general interest to be able to have different bluez config for different 
machines...
