Ah, I would say "Next, I will consider about MAKEDEV".
Before it, I must learn English....

Yes. I agree.
But, anyway, it's DEFINITELY IMPOSSIBLE to implement them SOON.
I know that many of you want auto-generation of MAKEDEV, the mechanism like
device filesystem and so on. But, I say again,
"The current NetBSD lacks some mechanisms to do it."
Certainly the patch kit of my proposal contains the auto-generaion of
device switches only, though it's one of the lack and it's very big even now.
Even if ok'ed to merge my patch kit, it's not so easy...
