This[0] is one of the more interesting reviews of this I've seen in a long time, including what seems like a footnote about dtrace at the end that I thought was a shocker.

(I hate it too, but that's no excuse to just ignore it.)
EDIT: Sorry, I accidentally downvoted you. Apologies.
What are those reasons, concretely? Would he be better served by choosing e.g. a BSD variant? There's a non-trivial cost to choosing a "not-completely-understood" license. Or, equivalently, there's value in choosing a well-known "standard" license. While the CDDL should probably be classified as "well-known" at this point, its interaction with other licenses isn't, and -- unless you're actively working against GPL-ish licenses -- it's to be avoided. You can get what what you want by chosing a BSD-esque license instead.
I think I agree with many of your other points, though. As I say, I'm not a lawyer and not overly fond of licensing in the first place. (Still doesn't mean you can ignore this concern, unfortunately! If only ignorance of the law were an excuse!)
EDIT: If you're going to downvote, please explain. I don't care about the numbers, but I would like to know why my argument is wrong/misguided.
Frankly, you're an elitist, who doesn't care about the use-cases of anyone but technical experts. For most users, the type of filesystem in use does not matter, nor does access to dtrace.
You were slagging off ubuntu and saying you don't know why people use their shit. I gave you a reason - in fact, ubuntu was responsible for a huge groundswell of interest in open source almost a decade ago, because of that user-friendly focus. That's a core part of why people use their stuff.
> What was so bad about Debian ?
1) Unpredictable upgrade cycles. 2)Packages in stable were a bit on the ancient side. Ubuntu LTS is awesome (other projects like Firefox have since copied the fixed release cycle)
> If you don't like Debian Why not give a a bsd a try
Because BSD had (has?) poorer driver support for consumer products (like on my dev laptop)
I don't care much for Canonical and some of their other projects (Unity desktop, Ubuntu One), but Ubuntu as a project is pretty kick-ass. Ubuntu stepped into desktop linux in a big way as other Linux vendors abandoned ship (see RHEL)
In this case, it's a mutual incompatibility. This is just as much about the CDDL's restrictions as it is the GPL. The CDDL was created after the GPL, and it was an intended incompatibility. The GPL could have been the MIT license and the CDDL might have included a "cannot be distributed with MIT-licensed software" clause.
The point is that now that nobody has an interest in keeping ZFS out of Linux, it's time to relicense! That's all there is to it.
Of course, you can't, which is why you're still following me months later posting impotent comments. I'm staggered how deep this bit, I really must have hit a nerve.
