Very nice post!
This is of great interest to me, so it is interesting to see the different attempts.
I notice you have your own definition of minimal here..it's a good thing no one is wasting time arguing over a definition you already provided, and complaining it is not something else :P
Regarding the minimal X install, I wonder about some of the packages, eg libXinerama, are they really necessary? I have quite a different list for a minimal X, and have not had so much time to test. In another thread, someone mentioned X does not actually need any X libraries. Is this correct? If so, what are the consequences of this...no applications, not even xterm would run?
Excellent post though
