Oracle probably thought they’d killed OpenSolaris after they bought Sun and focussed so many resources on Sun’s hardware business. But that sort of thinking would betray an ignorance of the reality of open source if it was true. You can shut down proprietary projects because you own them; open source projects only shut down when they have no community.
Instead, Oracle merely erased the name “OpenSolaris” from history and triggered the formation of the Illumos project. They thus created the environment for a whole range of new ventures based around the innovations that made Solaris 10 a great operating system. Read about them in my column in InfoWorld this week.
