Also from the FAQ:

"What about dual licensing? Can I license my code under the CDDL as well as another license?

Yes, if you are the copyright owner for the code you can choose to license under multiple licenses, including the CDDL."

Eric Schrock, a developer for Sun, posits his opinions on why the GPL would not be a good fit for Sun.

"Say I post an example of a function foo() to my website. Oracle goes and uses that function in their software. They make no changes to it whatsover, and are willing to distribute that function in source code form with their product. If it was GPL, they would have to now release all of Oracle under the GPL, even though my code has not been altered. The consumer's rights are preserved - they still have the same rights to my code as before it was put into Oracle. I just don't see why they have a right to code that's not mine."

I think his argument holds weight.

From the FAQ:

"Can code licensed under the CDDL be combined with code licensed under other open source licenses?

CDDL is file-based; that means that files licensed under the CDDL can be combined with files licensed under other licenses, whether open source or proprietary. However, other licenses may have different restrictions which may prevent such combination; be sure to read and recognize those."

So, it might be better to say the GPL is be incompatible with the CDDL. No fault in the design of the CDDL.

FAQ that is, as in the Open Solaris Licensing FAQ.

Let the flames begin ;-) How much do you want to bet that the majority of the "opensolaris is not as X as linux" and "CDDL is not as good as GPL" comments will come from pro Microsoft people?

Sun's CDDL is compatible with the GPL. It is the GPL that is not compatible with the CDDL.

Did you even bother to read the license? The http://www.opensolaris.org page even has a nice licensing FAQ. So there is no excuse not to educate yourself before posting. (:

The CDDL is far less restrictive than the GPL. Since it is a file based license it can be used in closed source code. It is completely different than the LGPL but from a proprietary developers point of view it has a similar restrictiveness. I'm a Linux developer and I like this license.

Why don't you have a look for yourself and give us the benefit of your experience...

And it looks to me as if it would be as easy/hard to put OpenSolaris bits into GNU/Linux as it would to do the reverse.

The CDDL is based off of the Mozilla license.

There's a FAQ on the new OpenSolaris site about licensing here:
http://www.opensolaris.org/faq/licensing_faq.html

Along with a summary of the changes from the Mozilla license:

And a redlined diff of what exactly has changed between the MPL and the CDDL (in a pdf file):

I work in the Solaris group. I can tell you plainly that Microsoft had nothing to do with this. Burying the hatchet with MS was a move which came long after we started the Open Source Solaris investigations and work.

You've drawn an invalid post-hoc conclusion (X before Y, so X must be the cause of Y). Please refer to the FAQ.

Bryan Cantrill, one of the DTrace developers wrote this blog entry as a general introduction to the source code layout and also to DTrace. This post by Adam Leventhal goes into some more detail.

82678 lines of C were made public. No registration, no click through license before download. The OpenSolaris FAQ is pretty good btw, and there's also a roadmap page.

According to this blog (the entry dated 15:43), those in the pilot program (more than 100 developers out side of Sun) have today gotten access to the entire Solaris source base, and have already built their own version - screen shot.
