Neither in menuconfig nor in xconfig do I see any place to actually select
INPUT. Help text suggests that it is a) selectable b) it can be made modules.
I do not have either option. Here what I see in menuconfig if I go into Input
device support:
--- Generic input layer (needed for keyboard, mouse, ...)
< > Support for memoryless force-feedback devices
--- Userland interfaces
as you see there is no check box for INPUT itself.
I already had similar issue something else (I believe it was something related
to serio). In menuconfig item was no selectable, but I could directly
edit .config to change y to m.
This may be related to
Symbol: INPUT [=y]
Prompt: Generic input layer (needed for keyboard, mouse, ...)
Defined at drivers/input/Kconfig:7
Depends on: EMBEDDED
Location:
-> Device Drivers
-> Input device support
Selected by: VT
and CONFIG_VT is indeed y (I do not think this even can ever be m). Still even
then this is way too confusing.
.config can be provided on request

... snip ...
somewhat off-topic, but when one has questions about oddities in the
configuration process, is it more appropriate to ask on *this* list,
or on the kbuild-devel list?
only two minutes ago, i posted this kind of question to kbuild-devel,
but now i'm wondering if i sent it to the wrong place. thoughts?

INPUT can only be unset if you set CONFIG_EMBEDDED=y.
The rationale is that it usually doesn't make sense for users to disable
INPUT, and allowing it tends to cause some confusion.

I do not want to disable it. I want to make it module (OK it has the same
rationale - if you need it anyway why you do want to make it module etc).
This should be possible according to help text. It does not work. Direct
editing of .config silently reverts it back to y instead of m.

Welcome to the wonderful world of the 'select' kconfig statement.
config VT
bool "Virtual terminal" if EMBEDDED
select INPUT
default y if !VIOCONS
This means if VT is selected, INPUT has to be 'y'.

What you want seems to require some non-trivial changes.
Are you trying this "just because it should work" or is there a strong
technical reason why you need it?

No, I do not have any compelling technical reason; I was just going via more
or less permanent .config cleanup round and was surprised why it did not work
because it did work before (but it was really long ago, I guess in late 2.5
times). When I tried it last time I was mostly driven by attempt to minimize
kernel size so it fitted for floppy boot. Since then it became less
interesting (it is probably won't fit anymore and distribution I use dropped
floppy boot support anyway).
Thank you (and Russel) for explanation and sorry if it was too trivial
question.
