Will Sun release OpenSolaris also under the GPL?

After releasing Java under the open source GPL license yesterday, Sun's senior vice president of software, Rich Green, hinted that the company might make the source code of the company's UNIX operating system available under the GPL license as well.

The availability of OpenSolaris under the GPL license would facilitate the inclusion of Solaris source code in the Linux kernel, something that can't be done with the CDDL license currently used by OpenSolaris.

Although many were skeptical last time Schwartz expressed an interest in licensing Solaris under the GPL, Sun has earned back credibility with the recent release of Java, and I think that the community will probably give them the benefit of the doubt this time.

By releasing Solaris under the GPL, Sun could finally eliminate the barriers that currently prevent interchange of source code between Linux and Solaris.
