[U17] configuration.xml location is fixed?

For some of our cad builds, we have user prefs in a custom location. All re-direction seems work well in U17, except for the configuration.xml file. From prelim testing, the file has to be correct and exist in the C:\Users\...\AppData\Local\Bentley\MicroStation\10.0.0\prefs\configuration.xml location for our cad build to work correctly.

Can someone from Bentley confirm that is the case? And if it is, is that supposed to be WAD or an oversight? 

Also, it would be greatly appreciated if a full documentation regarding the configuration.xml file be made available asap, including it's known limitations. The information provided in the post below is nowhere enough to integrate U17 into a production CAD system:


Example of missing information: the <Path> tag can be omitted and replaced by using the <ConfigurationVariable> tag, which is a far better option to use from an admin point of view.

Best regards,
