Because of the necessity of user interaction.

Correct and it _must_ be our goal that such changes do _never_ happen. 
There should be a way to preserve user settings without touching the 
contents of system files. Maybe we should just save the differrences to 
the original files and apply them to the freshly loaded files at system 
start.

Possibly, if apkg really detects all incongruities.

Of course

It will be easy to implement this although I do not like it. I will 
certainly look into a way to preserve user changes, but that will be 
major work and take some time.
