Linux Employees of Lawrence Livermore National Laboratory have ported Sun's/Oracle's ZFS natively to Linux. Linux already had a ZFS port in userspace via FUSE, since license incompatibilities between the CDDL and GPL prevent ZFS from becoming part of the Linux kernel. This project solves the licensing issue by distributing ZFS as a separate kernel module users will have to download and build for themselves.

They can't scrap CDDL'd code, but they probably wont opensource parts which are closed now, like SCC, Xsun, fishworks and such.

OpenSolaris is not selfhosting, you can't compile it without some proprietary libraries and there is some of "valued add" (or better say: Freedom subtract) parts, like mentioned fishworks.

Sun had plans to opensource that, and they also had plans to fix CDDL and remove choice of law clause in v2, making it acceptable license (look video for details). Oracle probably wont bother.

There is also problem with developer community... or lack there of. How many of OpenSolaris fans do serious kernel development? All kernel developers are at Oracle. If Larry moves them to proprietary Solaris version, OpenSolaris is toast. There is nobody to pick up development. 2009.6 will stay available, but how long will people use that? Oracle already discontinued paid support for OpenSolaris, there is now only proprietary Solaris 10 on their agenda. Or should I say SoLarry's.

I really liked Sun, but they really screwed with OpenSolaris licensing. If they used GPLv3, they would still be incompatible with Linux in start, but they would look good and see developers coming into their community and no Larry Elison could kill OpenSolaris. This way, OpenSolaris will be abandonware.

To all GPL bashers: That is what happen when you use GPL-incompatible license on purpose.
