You mean that what I've been happily using for eight months.
What would the different interface be, and what would the advantage be? (Are
you proposing a different file format?)

You've already made up your mind about the patch, based entirely on opinion
rather than technical arguments. I'm not convinced you've even read my list
of reasons for the patch. (You certainly haven't responded to any of the
actual reasons, such as failure to find the config file being grounds for a
build break with miniconfig but not for allnoconfig. You're already ignoring
that.)
If you'd like to ignore the rest, I'm not sure what real difference it would
make.

So far, this statement of pure opinion is the sum total of your technical
arguments.
I've been working around kconfig for most of a year to do this functionality,
until your recent changes broke what I'd been doing. Your recent changes
replaced the way I've been doing it with a new way of doing it, but I don't
believe you had what I've been doing all along in mind when you did them.
You primarily seem to have been interested in offloading decisions like
allyesconfig not enabling broken drivers not expected to compile. The fact
that it's useful to me seems entirely accidental.
Are you saying you had something like miniconfig in mind when you made these
changes? If so, why was there no documentation? Why was there no way to
make a mini.config from a normal config? Why was the user interface wrong in
several different obvious ways that were easy to fix? (You've already
admitted that the stdout output is useless, and O= should take the config
from the target directory.)
I was cheerfully using this functionality for eight months before you added
allno.config, and what you did is closer but not a perfect fit for for what
I've been doing.
> I'm trying to explain, what would be needed to do it properly,
What exactly does the patch I posted do wrong? (Other than the makemini.sh
being a hack, but it's a hack to replace a complete absence of this feature.)
You seem to be simultaneously arguing that allnoconfig by itself is so good
that it needs no change (despite there being no way at all to automatically
create a miniconfig from a big .config), and that supporting miniconfig is an
excuse for such an extensive rewrite that not just kconfig but kbuild must be
adjusted to compensate.
Pick one.

It was previously provided by
make allnoconfig && cat mini.config >> .config && yes "" | make oldconfig
Although that admittedly wasn't reliable because oldconfig is based on
defconfig rather than allnoconfig, but yes "n" could go into an endless loop
because oldconfig stupidly re-queries for numeric constants indefinitely.

Why? What advanced features?

If I wanted it to work just for me, would I have bothered writing up
documentation first thing? Would I have bothered posting the patch here at
all?
What situations does the patch I posted previously not work in?
