Linux "Today the ZFS on Linux project reached an important milestone with the official 0.6.1 release! Over two years of use by real users has convinced us ZoL is ready for wide scale deployment on everything from desktops to super computers."

Oracle inherited the CDDL licencing on ZFS/Dtrace from Solaris when they bought it. Now that they (Oracle) own ZFS they could re-licence it should they want to, instead they keep their ZFS enhancements proprietary and are continuing their efforts on their own GPL licenced BTRFS filesystem.

ZoL != OpenSolaris ZFS. ZoL uses ZFS from Illumos, which has many more copyright holders than just Oracle. You are encouraged to download the source and do a search for "Copyright (c)" lines, just to see how many parties would need to agree.

The reason Solaris licenced ZFS and DTrace under the GPL incompatible CDDL deliberately was because they were losing market share to Linux and obviously didn't want to 'give away' any advantages to their main competitor.

Thanks for sharing your interesting, though unsupported hypothesis.

No, again the reason they are incompatible with GPL is because that was a deliberate choice by Solaris when they licenced them as such to prevent Linux from using Solaris's 'crown jewels'.

Sun != Solaris. Minor mistake aside, you are merely asserting your claims without evidence. Claims made without evidence can be dismissed without evidence.

Oracle created BTRFS, companies like Red Hat, IBM, Intel have worked on SystemTap. They did this because they can't legally ship Linux with ZFS or DTrace, and therefore won't, even if some guy named 'saso' on OSNews says that 'there's no legal risk'.

Interestingly enough, some guy named Valhalla on OSNews makes baseless unsupported claims about people's and companies' intent and then turns around and criticizes me for expressing my personal opinion (which I even labeled as such). Kettle meet pot.

Yes, but Oracle's version of ZFS, the one they got when they bought Sun and are now developing in a proprietary fashion is theirs to re-licence if they so wish.

Claims made without evidence can be dismissed without evidence.

Same goes for your claims.

Of course mine are not taken straight out of the air, Danese Cooper who was apparently the one who wrote CDDL while at Sun stated that it was written to be GPL-incompatible.

Draw your own conclusions, but really given the statement from the person presented as having created the licence aswell as how it makes perfect sense for Sun to not want Linux to snap up their coveted tech there is no doubt in my mind that this is so.

Hardly baseless, read the Wikipedia link and watch the video if it's still linked.

Your statements that Oracle, Red Hat, Intel, IBM, created/worked on BTRFS and SystemTap out of 'religious nuttery' is indeed baseless, as is your statement that no one will be sued for shipping licence infringing code.

Also, when did Ubuntu start shipping proprietary drivers with Ubuntu? Last I checked (which was admittedly a long time ago) they shipped no proprietary binaries, once you had installed Ubuntu and was online you where informed that there were proprietary drivers available for your system and that you could download and install them from a repository should you want to, but they were not shipped on any installation media nor installed by default.

Again, that's not the version in ZoL. Therefore, Oracle re-licensing their bits isn't enough.

Of course mine are not taken straight out of the air, Danese Cooper who was apparently the one who wrote CDDL while at Sun stated that it was written to be GPL-incompatible.

Nor are mine. Danese Cooper says one thing, some Sun engineers say otherwise. I didn't take a position in this, I even specifically said: " Depends on who you ask. Some people say it was, some people say it wasn't." Stop tearing down straw men.


It's funny you should quote that, because apparently you didn't read the whole section. Read a bit further down on how Simon Phipps disagreed with what Danese said. All this goes to support my statements, that there were mixed feelings on this even within Sun, and to negate your position that it was a clear cut deal.

Draw your own conclusions, but really given the statement from the person presented as having created the licence aswell as how it makes perfect sense for Sun to not want Linux to snap up their coveted tech there is no doubt in my mind that this is so.

No doubt in your mind? I can see that - that's the religious bit I was referring to. You come to a fixed conclusion and find evidence to support it. I, for a change, don't know - it might have been, it might not.

Your statements that Oracle, Red Hat, Intel, IBM, created/worked on BTRFS and SystemTap out of 'religious nuttery' is indeed baseless,

I don't mean to say that everybody who works on these are religious nuts, only some are (such as yourself) - I should have qualified that, mea culpa.

as is your statement that no one will be sued for shipping licence infringing code.

Opinion != statement of fact. Read what I wrote again.

Look dude, you seem hell-bent on making this a discussion about he-said-she-said. I've got better things to do than argue about with people on the net. Talk is cheap, what matters is code.
