It seems to me that while depending on ordering for definitions, files, &c., may be no good, for selections the language of include "GENERIC" no options DIAGNOSTIC no agp* is still valuable.
I don't mind how it's implemented, but my main concern is that I want an example like the above to "work". I want it to mean: my kernel should be based on GENERIC with some changes; whether or not "options DIAGNOSTIC" is present in GENERIC, my kernel should not have "options DIAGNOSTIC"; and whether or not anything related to agp is present in GENERIC, my kernel should not have any agp devices (and should not have anything that depends on agp). I do not want error messages like "options DIAGNOSTIC was already off, so you are not allowed to try to turn it off again" or "there were no agp devices, so you are not allowed to try to remove agp devices".
So config(1) ought to choose whatever is the last yes/no answer for a selection in order to decide what things are really enabled or disabled, and then process dependencies recursively from there, rather than incrementally processing dependencies as the parser makes progress.
That sounds as though it would do what I want. --apb (Alan Barrett)
