Sure. But at least it is necessary to say for WHICH boards it is necessary.
To load it into RAM as a default case is NOT a satisfying solution!

Sure. But I guess we need a tool or something else to clear up WHAT card nedds WHAT frontend module. If there is LIGHT instead of DARKNESS (or grey zone) in this issue no mailing list be flooded at all with any complaints.

YUP. Sure. But I do not want to keep it as regular state. I want a concept where it is avoided to be loaded into RAM when it is NOT necessary at all.

NO! I only showed that there are cases in which those static dependencies are obsolete. That is why I call this backend concept reactionary. It fills up your RAM with modules that are not needed. The concept generalizes the need of those three modules FOR ALL cards. And to object to that I have taken the pain to show at least ONE PROVEN CASE where this generalization is complete nonsense! WHEN WILL YOU UNDERSTAND THIS, MR. CHEHAB??
> Without those, several boards will stop working.
YES, Mauro: SEVERAL, BUT N O T A L L !!!!!!! That's why the concept needs to be overworked! You are arguing as if all boards would need that stuff, and this argumentation path is WRONG! FALSE!!

I only say that I am not convinced of the capabilities of the mentioned person, and that he has been causing lots of trouble in the past. What is wrong about that? It is a fundamental democratic right to say openly and freely what your personal opinion is. And apart from that I still would like to know what DST is: a frontend, a backend, or an UFO (unknown flying object). Noone knows! completely conceptless and chaotic, isn't it?
Thanks for your "open-mindedness", my dear majesty!
