Improvements include a performance-enhanced TCP-IP stack to shed the "Slowaris" moniker and their much-vaunted ZFS (Z File System). Solaris will initially be "free" (as in beer with an annual subscription fee for bug fixes and support), and will reportedly be released under an open-source license later." As well, KingSkippus writes "MSNBC reports, "After investing roughly $500 million and spending years of development time on its next-generation operating system, Sun Microsystems Inc. on Monday will announce an aggressive price for the software -- free. Sun also has promised make the underlying code of Solaris available under an open-source license, though the details have not been released."
