Yeah, it sure should be interactive. This was pasted from my automated testing
that isn't interested in unbootable kernels.

So it should be something like:

config GENERIC_BOOTABLE_CONFIG
bool "Enable kernel options that are needed to boot typical Linux distributions"
default y
...

(I removed the 'SANE' naming as disabling this option is obviously not 'insane'.)
