and bug fixes, and more applications, but may not have undergone extensive testing. Production releases were branched from a snapshot of the development codebase (following a code freeze) and underwent a QA process that includes backporting security updates and bug fixes. OpenSolaris can be installed from CD-ROM, USB drives, or over a network with the Automated Installer. CD, USB, and network install images are made available for both types of releases. Repositories OpenSolaris uses a network-aware package management system called the Image Packaging System (also known as pkg(5)) to add, remove, and manage installed software and to update to newer releases. Packages for development releases of OpenSolaris were published by Oracle typically every two weeks to the /dev repository. Production releases use the /release repository which does not receive updates until the next production release. Only Sun customers with paid support contracts have access to updates for production releases. Paid support for production releases which allows access to security updates and bug fixes was offered by Sun through the /support repository on pkg.sun.com. Documentation A hardware compatibility list (HCL) for OpenSolaris can be consulted when choosing hardware for OpenSolaris deployment. Extensive OpenSolaris administration, usage, and development documentation is available online, including community-contributed information. License Sun released most of the Solaris source code under the Common Development and Distribution License (CDDL), which is based on the Mozilla Public License (MPL) version 1.1. The CDDL was approved as an open source license by the Open Source Initiative (OSI) in January 2005. Files licensed under the CDDL can be combined with files licensed under other licenses, whether open source or proprietary. During Sun's announcement of Java's release under the GNU General Public License (GPL), Jonathan Schwartz and Rich Green both hinted at the possibility of releasing Solaris under the GPL, with Green saying he was "certainly not" averse to relicensing under the GPL. When Schwartz pressed him (jokingly), Green said Sun would "take a very close look at it." In January 2007, eWeek reported that anonymous sources at Sun had told them OpenSolaris would be dual-licensed under CDDL and GPLv3. Green responded in his blog the next day that the article was incorrect, saying that although Sun is giving "very serious consideration" to such a dual-licensing arrangement, it would be subject to agreement by the rest of the OpenSolaris community.
