What makes this feature interesting is that it was the reason for the 
problem of "#8108: Extension configuration options are not always shown".

The problem was:
  - The userFunc in extconf should be executed during installation of an
    extension
  - But: userFuncs can only be used AFTER the extension is actually
    installed
  - Therefore the extension installation now needs to be done in two
    steps, first the installation, and then the step where a userfunc can
    hook into.

cheers
Ingmar
