Re: Possibly offtopic : Binary only driver

They won't. Why should they? Availability of source code is useful
primarily to those who can read and write programs. That's not the
majority of the worlds population.

They could support kernels with binary only modules. Other OS vendors do
it. Other open source projects do it. They choose not to however.

Good question! I thought it was because the kernel developers wanted to
make a kernel useful for desktop systems, but if that isn't the case then
I guess I have no arguments left: this whole thing revolves around wanting
the kernel to be easier to use and therefore more useful than it currently
is.

I saw that debate. Gregs arguments struck me as very poor, and I wasn't
the only one:

He basically said things like "Well Windows has multiple USB interfaces
and that's a bad thing" and expecting it to pass as assertion, ie there
was no analyis of why it was a bad thing. He just took it as read that it
was. In this case the cost of having the old interfaces (in financial
terms) was presumably outweighed by the benefits of retaining backwards
compatibility, otherwise MS would not have done it.

Remember, one mans bloat is another mans ability to upgrade ...

Yes, because as we all know software magically rewrites itself while we
sleep. Our IT systems are also upgraded by leprechauns.

That is unrelated to backwards compatibility. The rest of your paragraph
is based on an unsupported assumption: that Linux could not be
fast/multi-arch etc without an unstable module API. I've never seen
anybody seriously try and argue that (Windows NT kernel is also
multi-arch).

Anyway, this is all a pointless discussion. This is not me saying
"binary modules are good", I never claimed that, I'm saying they're
unavoidable and should be supported. 

I'm 99% convinced though that kernel policy will never change, no
matter how many people ask for it and no matter what their arguments
are.

Probably, the only way we're going to get a sane ISV-supportable desktop
system is by forking the kernel at the start of major release cycles (2.4,
2.6 etc). So this whole discussion is pretty useless and I wish I had
never started it, people here are far more interested in theoretical
performance benefits being available RIGHT NOW than eg being able to buy a
working wireless card.
