Ok, so let's step back a bit here: I've added this option with the idea
to have it as a shortcut so that you don't go search for every commodity
option when you want to boot the kernel as a kvm guest. Currently I have
it in all.config when doing randconfig builds here. While I'm doing the
randbuilds, why not boot it in kvm too while at it.

Now, I really fail to see what you describe above to be a fairly normal
use case. I'm sure you can take Kconfig and abuse it so that it screams
all kinds of errors and we know select is evil and Kconfig is not
perfect, etc, etc...

So I'm pretty sure we won't be able to plug all holes. However, let's
try to plug only those which hinder *real* usage instead of contrived
stuff.

So, let's start again: is this something real you're triggering
with some random testing you're doing or are you simply
abusing^Wexperimenting with Kconfig and staring at what breaks?

Thanks.
