OpenSolaris is an open source project created by Sun Microsystems to build a developer community around Solaris technology. It is aimed at developers, system administrators and users who want to develop and improve operating systems. As of June 2007, more than 60,000 community members are registered on opensolaris.org with around 2,000 members being employed by Sun Microsystems. An active OpenSolaris User Group is now growing worldwide, and dozens of OpenSolaris technology communities and projects are being opened on opensolaris.org.
OpenSolaris is derived from the Unix System V Release 4 codebase, and has significant modifications made by Sun since it bought the rights to the codebase in 1994. It is the only open source System V derivative available. Open sourced components are snapshots of the latest Solaris release under development. Future versions of Solaris will be based on technology from the OpenSolaris project.
On March 19, 2007, Sun made the surprise announcement that it had hired Ian Murdock, founder of Debian, to head "Project Indiana". Murdock later revealed the project as "taking the lesson that Linux has brought to the operating system and providing that for Solaris", making a full OpenSolaris distribution with GNOME and userland tools from GNU plus a network-based package management system. 
On December 1, 2008 OpenSolaris 2008.11 was released. It can be booted as a Live CD or installed directly. It uses the GNOME desktop environment as the primary user interface. The release also includes the ZFS file system, a filesystem with advanced snapshotting capabilities.
