| Well, the story I'm hearing on the Gentoo mailing lists (I don't

That's fine for a home user. What about a kernel hacker, a distributor,
a business, people who have to clean up after this mess. . . .

| A poorly managed IT operation can wipe out a business, whether the
| "production server" is Windows-based, RHEL-based, Tru64-based,
| Solaris-based, "woody"-based or Gentoo-based. Much as I hate Windows, I

Not at all

I'm claiming that an IT infrastructure that has to support 2.6 as-is
will be wildly more complex and more expensive than one supporting a
truly stable one with the same efficiency. It keeps changing. New
features must be added that aren't amply tested (and due to the 2.6
development structure, ample testing before mainline integration is much
more difficult).

|>Linus hates microkernels :o
| When Linus chose the "monolithic yet modular" approach for Linux over
| the microkernel approach, the state of the art in compilers and hardware
| was on his side. We're talking 386, GCC 1, right? It was the correct
| decision. I don't think he "hates" microkernels (Linus, correct me if
| I'm wrong :), he simply made an implementation decision to go another
| way. Again, I'm a dreamer. :)
| By the way, I never owned a 286 or 386. I went straight from 80186/DOS
| 5.0 to a Pentium MMX running Windows 95. I missed out on a lot of fun,
| eh?

Ask Linus to start making 3rd party binary module support a reality then.
