![]() ![]() And then there is a catch about derivatives the source of anything that is deemed to be a derivative work of the program has to be also available under the same licence. ![]() #OPENZFS LINUX DISTRIBUTION CODE#The GPL has a viral quality about it: one can modify the code to one's heart's content, but if the finished product is distributed, then the changed source code has to be offered as well. Īnd so, we come to the question of licensing. Instead, Oracle uses btrfs which was developed by Chris Mason, an Oracle employee who later moved to Facebook. The company has chosen not to use ZFS in its own GNU/Linux distribution – what it calls Unbreakable Linux and which is basically Red Hat Enterprise Linux repackaged. Then in 2010, Oracle swallowed up Sun and became the owner of the ZFS filesystem. Company apologists like the then chief open source office Simon Phipps were adept at covering up when asked direct questions about the seeming lack of direction. Even as late as 2009, Sun was in denial about its open source efforts, and acting as though everything was hunky-dory. Making a code contribution to OpenSolaris was a bureaucratic nightmare. ![]() The licence under which OpenSolaris was released - the Common Development and Distribution Licence - while satisfying the requirements of being an open licence, did not quite catch the imagination of the open source community. It was released in OpenSolaris, Sun's bid to attract developer and user interest in Solaris, in 2007.Īlas, it was far too late to attract attention from the mass of open-source developers. Like many other technologies it developed, Sun hung on to ZFS and then released it under some kind of open licence at a time when it would make little difference to the company's future. And some years ago, I interviewed a sysadmin who runs FreeBSD on his servers and makes extensive use of ZFS. Debian also offers it as an option, though not the default. Ubuntu is one Linux distribution which offers ZFS during installation when Canonical, its parent company, decided to offer ZFS as default in 2016, it was accused of violating the GNU General Public Licence version 2, the licence under which the Linux kernel is released. ![]()
