Sure, but why should they have to? What technical reason is there
for not including it, Linus?

I completely don't understand your reasoning here. I use it for my
home, not for work, and that's important for me. And not everyone
can spend their evenings rolling up the next set of patches for
a distribution. Yes, vendors want it, they need it, but there are
plenty of people like me that want this in too!

We want to see this in the kernel, frankly, because it's a pain
in the butt keeping up with your kernel revisions and everything
else that goes in that changes. And I'm sure SuSE, UnitedLinux and
(hopefully) Red Hat don't want to spend their time having to roll
this stuff in each and every time you roll a new kernel.

I mean, PLEASE, Linus, what do we have to do? There are so many
interests in this stuff, and I really, truly don't get what's wrong
with putting this in the kernel?

Have you looked at it? Have you looked at how it is now structure
to be non-invasive? How it will allow other kernel developers to
generate their own dumping methods? I mean, we sent you E-mails
weeks ago, and you didn't respond to any of them with even a word
of acknowledgement of receipt.

I do. Others like myself do. And not just for development
purposes. I don't like to see my system crash after installing one
of your new kernels and not be able to figure out what's wrong.
The nice thing is that LKCD there, it works, and I can just look
at the crash report instead of wishing that my console buffer
didn't just scroll off. Oh, I know, I'll just wait for it to
happen again ... yeah, like that's real intelligent.

Other vendors have merged LKCD a long time ago and use it, and
expect it to be there. And users like myself find it valuable on
their desktops, their servers, etc. I mean, there's someone using
this at Purdue that's responded to you, just another kernel user
that likes to have this stuff there automatically.

TurboLinux, MonteVista, Veritas, SuSE, and UnitedLinux have LKCD.
With the most recent changes, I think Red Hat can put LKCD in now
such that it isn't invasive to their distribution.

I think SuSE has already expressed a desire to have this in. If
you want to hear from others, I'll asked them to respond to you.
