Sun considers GPL license for Solaris

Sun may be selling servers running Linux, but that doesn’t mean it is cutting back on the evolution of Solaris. Among its plans, the company is considering offering a free, open source version of its flagship operating system, and offering Solaris with a version of its Java Desktop System, said Jonathan Schwartz, the company’s recently appointed president and COO.

“Maybe we’ll GPL it,” Schwartz said of Solaris, referring to the GNU General Public License under which the Linux operating system is distributed. “We’re still looking at that.”

In a wide ranging interview in San Francisco Friday morning, Schwartz described a number of initiatives in the works intended to make Solaris more competitive with Linux, which has been taking market share from the low end of Sun’s product line.

Until now, Sun has made Solaris freely available to certain non-commercial users, but it has not released the Solaris source code, and still charges $99 for a single-processor license. Adopting the GPL would dispel criticism “that if you can’t build your own kernel, then you’re not open,” said Schwartz, calling that notion “a fantasy.”

“I just find that kind of comic,” he said. “Open standards are all about enabling more competition, not about enabling CIOs to have more source code. They don’t want more source code,” he said.

Though Sun executives have been cool on the GPL in the past, Schwartz said there was “not a lot” preventing Sun from releasing Solaris under the GPL. It would offer support contracts as an option, in a model similar to that of Red Hat. “We view the GPL as a friend. Remember, (Sun) was built off of BSD and the BSD license,” he said, referring to the open-source Berkeley Software Distribution license.

Still, Sun has its apprehensions. “What worries us about the GPL is its capacity to encourage forking, because what’s happened in Linux is that Red Hat has forked. Not in the sense that the kernel is different … It’s forked because if you write to the Red Hat distribution, you can’t go and run on Debian.”

Sun will likely move “very quickly” to a free licensing model where Solaris revenue would come from a paid subscription, Schwartz said. He wasn’t specific about when this might occur or what the pricing of such a model might be, other than to say it would be “less than Red Hat.”

In fact, with an open source version of Solaris and a subscription licensing model, Sun’s model for selling Solaris would become very similar to how Red Hat sells Linux, Schwartz said. “We wouldn’t be different, except we would be driving open standards, because our fundamental objective is to promote the standards agreed to by the community to drive a broader market, not trying to fork it,” he said.
