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.
