So I'm looking at menuconfig and contemplating rearranging the heck out of it
to slather some calamine lotion on one of my longstanding personal itches.
(You may have seen a couple trivial patches float by.) I thought it would
be polite to ask about a couple of things before trying anything major:
1) There are no actual options at the top level, and I'm wondering if that's
policy or coincidence. For example, CONFIG_EXPERIMENTAL lives by itself in a
wrapper menu that's pretty darn specifically tailored to it, and is unlikely
to grow too many more options. Would taking it out of the wrapper menu be a
bad thing?
2) There's at least two different menu types. The standard top-level menus
are just "descend into this" (the "menu" type), often with a guard item at
the top of the menu you descend into that deactivates and hides everything in
it. But a couple (like CONFIG_EMBEDDED, under general setup) are type
"menuconfig", where you have to select the menu in order to be able to
descend into it. These two are basically functionally equivalent,but provide
have two different user interface styles. Which is preferred? (The
menuconfig type is more straightforward and more compact, but also slightly
easier to miss the need to descend into something and configure stuff. Is
there some kind of subtle policy here, using one to indicate a pure guard
item with no associated functionality (which only affects the configurator
and not generated code), and the other to indicate associated generated code
is attached? Or what?)
4) Some menu guards don't actually disable everything in their menu when you
switch 'em off. The CONFIG_INPUT is one example, CONFIG_VIDEO_DEV is
another.
5) Is the indentation level supposed to mean something? Look at PCI IDE
chipset support, for example. Disable it and the indented menu items under
it disappear, along with a dozen or so menu items underneath it that aren't
indented. Am I missing a subtle policy issue here? (It makes cases like
"does USB Gadet support need USB Support, cause it doesn't go away when you
disable it" harder to figure out...)
6) In test-2, if you do a make distclean (zapping your .config) and also rip
the config out of /boot, and then do a make menuconfig, you get the
following:
boolean symbol BINFMT_ZFLAT tested for 'm'? test forced to 'n'

This is a bad thing, yes?
