Developers and solution providers might get more than they expect when Sun Microsystems details its plans to open-source Solaris later this year. Sources familiar with the company's plans told CRN at JavaOne 2004 that Sun is not going to simply open up bits and pieces of the millions of lines of code in Solaris, Sun's popular Unix-based operating system.
