Late 2.5, and all of 2.6 development is done radically different than
2.4 was. Basically, we are going to continue to do nothing differently,
other than pointing out to the world, that we are operating quite
differently than people really think we are.
I'm going to try to hijack my OLS talk tomorrow (krefs, bah, how boring)
to talk about this in more detail, given the apparent lack of
understanding. I'll post a link here to my presentation when I write it
up (I still have a few hours...)

Stable is in the eye of the user. 2.5 was incredibly stable for me,
depending on what task I wanted to do at the time :) It's all relative,
and perception. Bah, I just described marketing, someone shoot me...

A certain 3 letter company just put the next 2.6 enterprise Linux kernel
distro release through more testing the past few months than it ever has
had in the past. I know this based on the bugs that were found, which
had been there since at least 2.4.0. Hopefully we can run that test on
every release, and a smaller subset on every nightly snapshot.
I know another big company which has recently acquired a few Linux
companies, that also has an incredible test department due to their
prior product offering, that is now starting to be revamped over to test
Combine that with the small thousands of people who build their own
kernels from kernel.org when every new release happens, with their odder
build options, and we have the start of a really giant regression test
suite that will ensure that we don't break anything major, and not
realize it quite quickly.

Hahahaha. That Debian kernel is full of patches. Slackware is the
closest I've seen, and Gentoo now only has 4 things added to their
kernel (not including bug fixes that are already in the current tree,
that will be thrown away with the next release.) And as I'm the
maintainer of that package for them, I'm trying to get that down to 0.
 For those interested they are:
and I think I'll drop supermount next to see who screams...
