Umm. You are making the fundamental mistake of thinking that Sun is in
this to actually further some open-source agenda.
Here's a cynical prediction (but backed up by past behaviour of Sun):
- first off: they may be talking a lot more than they are or ever will
be doing. How many announcements about Sun and Linux have you seen over
the years? And how much of that has actually happened?
- They may like open source, but Linux _has_ hurt them in the
marketplace. A lot.
They almost used to own the chip design market, and it took quite a
long time before the big EDA vendors ported to Linux (and x86-64 in
particular). But when they did, their chip design market just basically
disappeared: sparc performance is so horribly bad (especially on a
workstation kind of setup), that to do chip design on them is just
idiotic. Which is not to say that there aren't holdouts, but let's face
it, for a lot of things, Solaris is simply the wrong choice these days.
Ergo: they sure as hell don't want to help Linux. Which is fine.
Competition is good.
- So they want to use Linux resources (_especially_ drivers), but they do
*not* want to give anything back (especially ZFS, which seems to be one
of their very very few bright spots).
- Ergo: they'll not be releasing ZFS and the other things that people are
drooling about in a way that lets Linux use them on an equal footing. I
can pretty much guarantee that. They don't like competition on that
level. They'd *much* rather take our drivers and _not_ give anythign
back, or give back the stuff that doesn't matter (like core Solaris:
who are you kidding - Linux code is _better_).
Completely agreed :-)
End result:
- they'll talk about it. They not only drool after our drivers, they
drool after all the _people_ who write drivers. They'd love to get
kernel developers from Linux, they see that we have a huge amount of
really talented people. So they want to talk things up, and the more
"open source" they can position themselves, the better.
Definitely. They already began to pull some people like Ian Murdock. And
I'm really very disappointed of this move,Ian did. Especially, such a
person who has very good reputation and high profile in the Linux
Community. He immediately shut down his company (also leaved
Linux-Foundation) and joined to sun. After joining, he made statements
like "How to make Solaris more like Linux ?" etc. Like a 40 years
employee at Sun. Another interesting thing is the timing of this hiring.
So, this situation is a good example of it.
- They may release the uninteresting parts under some fine license. See
the OpenSolaris stuff - instead of being blinded by the code they _did_
release under an open source license, ask yourself what they did *not*
end up releasing. Ask yourself why the open source parts are not ready
to bootstrap a competitive system, or why they are released under
licenses that Sun can make sure they control.
So the _last_ thing they want to do is to release the interesting stuff
under GPLv2 (quite frankly, I think the only really interesting thing they
have is ZFS, and even there, I suspect we'd be better off talking to
NetApp, and seeing if they are interested in releasing WAFL for Linux).
Yes, they finally released Java under GPLv2, and they should be commended
for that. But you should also ask yourself why, and why it took so long.
Maybe it had something to do with the fact that other Java implementations
started being more and more relevant?
Am I cynical? Yes. Do I expect people to act in their own interests? Hell
yes! That's how things are _supposed_ to happen. I'm not at all berating
Sun, what I'm trying to do here is to wake people up who seem to be living
in some dream-world where Sun wants to help people.
So to Sun, a GPLv3-only release would actually let them look good, and
still keep Linux from taking their interesting parts, and would allow them
to take at least parts of Linux without giving anything back (ahh, the
joys of license fragmentation).
Of course, they know that. And yes, maybe ZFS is worthwhile enough that
I'm willing to go to the effort of trying to relicense the kernel. But
quite frankly, I can almost guarantee that Sun won't release ZFS under the
GPLv3 even if they release other parts. Because if they did, they'd lose
the patent protection.
And yes, I'm cynical, and yes, I hope I'm wrong. And if I'm wrong, I'll
very happily retract anything cynical I said about Sun. They _have_ done
great things, and maybe I'm just too pessimistic about all the history
I've seen of Sun with open source.
The _good_ news is that Jonathan Schwartz actually does seem to have made
a difference, and I hope to God he is really as serious about
open-sourcing things as he says he is. And don't get me wrong: I think a
truly open-source GPLv3 Solaris would be a really really _good_ thing,
even if it does end up being a one-way street as far as code is concerned!

One more time,agreed ;-)
