Well, if we can't determine whether a config option's set or not, if
it's not critical (ie, it's ~CHECK), then we warn.  If there's any hard
checks, then we error out I suppose.

Ah cunning, I'll have to try that...

Sure, as long as I sure I know how we're fixing them, I'd be glad to
help.  5:)  I'd just be fixing the userspace ones to make sure they're
~CHECK or would I be doing something else as well?  Also should I do
that via bugs and a week's grace period, or would you recommend I just
dive right in?

Ok, presumably USE=-modules will also stop the kernel checks, otherwise
the following could occur.  Let's say the foobar package builds external
modules and explicitly requires that foobar not be set in the kernel.
With USE=-modules, there's no internal version and there's no external
version, but the kernel package is installed, and the deps are happy,
even though they'll bug out when it's showtime.

Presumably there's also packages that aren't split, or depended on,
where not installing the modules is never a good idea.  Is there still a
way to disable the USE flag, or will it be a requirement of the
linux-mod package?

That's fine, just so long as it's on and not off, I don't mind what
system we use to do it.  5:)
