OpenIndiana Picks up Where OpenSolaris Left off
For those disappointed by Oracle's decision to discontinue supporting a free version of its Solaris Unix-like operating system, a new alternative emerged to take its place. OpenIndiana is part of the Illumos Foundation. OpenIndiana will be built on the last available version of OpenSolaris and will contain bits of Solaris 11. OpenIndiana is the new OpenSolaris.
OpenIndiana is said to be compatible with Solaris 11 and Solaris 11 Express and should be an easy drop-in replacement for those systems. Initially OpenIndiana will contain some closed-source code since the current code-base is not fully open. These bits will eventually be replaced by fully Open Source code.
OpenIndiana was born out of the need of many companies who relied upon Solaris and OpenSolaris for their businesses.
