And I did, and it's obvious that creating a single file along with the
~10 we already create in /sys, instead of running through /sys or
/proc later and reconstruct what we missed, is always, and in every
case faster and simpler. It gets rid of a bunch of things we need to
do today, and depending how much of the things you remove, you get
faster. It's a different model and hard to compare directly. But for a
fact, you can never be faster than the kernel provided nodes.

What exactly do you find is "crap"? What do you mean with "management"?

I also did, in exactly this thread.

I did in a reply to your earlier mail. And also mentioned the
init=/bin/sh case, which I think, would be reason enough alone,
without all the other gains, to do that.

Nobody says such thing. I just defend against "dog-slow", "backroom",
and the proposal of even more broken hacks to solve this very problem.
There is no hammering at all, it's just my personal discomfort with
replies who ignore the real issues, and bring up false facts.

You might be right here, I don't disagree. It's becoming more a
personal issue than a technical, and sorry for that. But stuff like
this happens sometimes, and it's also sometimes "how the kernel
project works". :) Again, sorry.

Come on. You can not convince Greg about anything, just because you
happen to work for the same company. Many of us share a company with
others, also you did in the past and you do now - and we will get
nowhere bringing up such conspiracy statements.

We came up with this, because we think it is the right thing, and it
has proven to solve our problems, and I'm personally still convinced
it is the best option, that's all.
