Right now, the use of an answer file forces the text mode for tl-setup, since that was the easiest way forward. In the future, we should probably extend the pygtk gui to allow for use of a answer file too. This would be made much easier with the implementation of bug 4232.
Why? This seems unnecessary - suggesting WONTFIX. Assigning to "---" for discussion in case I miss something.
Unclear purpose, so closing this.
