I don't think all the _details_ may be intentional, but the fact that make oldconfig "just works" is definitely a good thing. > "make ARCH=i386 allnoconfig" hides the prompt > of 64BIT. > > Then, "make oldconfig" makes the prompt newly visible, > so it is asking for user input. The "hides the prompt for 64BIT" is just a technical detail. It could equally well be a pre-determined Kconfig fragment that is used to generate a particular Kconfig. But once you *have* that particular Kconfig, I do think that "make oldconfig" should just work. And it apparently used to. So I think this is a behavioral regression. Linus
