Details of the open source move are available at the OpenSolaris developer community site. The site carries the Solaris source code, a new source browser, build tools, documentation, a community portal, mailing lists and developer blogs that carry further technical information.
The OpenSolaris source code includes the core operating system, networking, system libraries and commands. Sun plans to open source other components of the Solaris OS, such as the installation tools.
The OpenSolaris source base currently stands at 10 million lines of code and Sun says this will expand as developers contribute further applications using the Solaris OS.
Sun promised to make Solaris open source at the beginning of the year and in the meantime it has been distributing specific open source tools to prepare the developer community for the launch. The source code is available for the SPARC platform and x86/x64 platforms
