initdev sounds good to me. Given that we're adding a new and distinct
concept which will remain with us for a long time, we should name it
with care.

OK, so "initdev" could be viewed as meaning "a device which /sbin/init
needs"? Even I can understand that.

But /sbin/init isn't the first userspace we run, is it? There's
initramfs stuff, firmware loaders, etc.

What's the story here? Do we intend that all initdevs be up and
running before _any_ userspace runs? Or is /sbin/init the red line?
