it actually means that you can not count on this prefix. It might change
and it is perfect legal that it changes from one run of the daemon to
another. The variable prefix is discovered via some defined initial
method.

Remember that I intermixed the PID in the object path of BlueZ. Simple
because people started hardcoding object paths.
