SunOS is, in a sense, the predecessor to Solaris, Sun's current operating system. Unlike Solaris, which is based primarily upon System V, SunOS is based extensively on BSD, and by the 4.x releases, being based heavily on 4.3 BSD. For this reason, SunOS 4.x maintained some extremely loyal users into the 21st century, long after Sun had moved their entire base to Solaris. Sun finally discontinued support for SunOS in 2003.
