A new group announced Tuesday aims to create a community-built and -maintained version of Oracle’s OpenSolaris operating system in which all portions of the code are open and fully available for use by developers. Called “Illumos,” the new project will replace the closed portions of Oracle’s OpenSolaris code with open versions, making it possible for developers to create their own solutions based on the software. “Right now, it’s almost impossible to build derivative products from OpenSolaris,” said Garrett D’Amore, tech lead for the Illumos project.
