So, perhaps we're better off by just skipping defconfigs?

See https://lkml.org/lkml/2012/1/18/355 . Manually configuring from
scratch is, I think, simply not doable. About the only advice I'd dare
to give someone would be: somehow get a .config that works for your
machine, however old that .config might be, and use it as your base.
Probably by doing
    yes "" | make oldconfig >/dev/null

So I guess my question is: is a defconfig to be considered a ".config
that works for your machine"? And, yes, I realize "works" is a very
broad goal.
