Yes. The XML file describing the workflow the pattern brings.

The workflow must be defined the way that it will properly run which wizard is 
needed.  It can check which dialogs to run depending on packages which are 
installed. In your case, if the pattern contains both sendmail and postfix, 
it should ask user in the first step. Obviously if we ship sendmail and 
postfix, user selects this pattern but installs eg. qmail, the pattern 
workflow cannot take care of it.
