The Rise & Development of Illumos
Fork Yeah! The Rise & Development of illumos Bryan Cantrill VP, Engineering [email protected] @bcantrill WTF is illumos? • An open source descendant of OpenSolaris • ...which itself was a branch of Solaris Nevada • ...which was the name of the release after Solaris 10 • ...and was open but is now closed • ...and is itself a descendant of Solaris 2.x • ...but it can all be called “SunOS 5.x” • ...but not “SunOS 4.x” — thatʼs different • Letʼs start at (or rather, near) the beginning... SunOS: A peopleʼs history • In the early 1990s, after a painful transition to Solaris, much of the SunOS 4.x engineering talent had left • Problems compounded by the adoption of an immature SCM, the Network Software Environment (NSE) • The engineers revolted: Larry McVoy developed a much simpler variant of NSE called NSElite (ancestor to git) • Using NSElite (and later, TeamWare), Roger Faulkner, Tim Marsland, Joe Kowalski and Jeff Bonwick led a sufficiently parallelized development effort to produce Solaris 2.3, “the first version that worked” • ...but with Solaris 2.4, management took over day-to- day operations of the release, and quality slipped again Solaris 2.5: Do or die • Solaris 2.5 absolutely had to get it right — Sun had new hardware, the UltraSPARC-I, that depended on it • To assure quality, the engineers “took over,” with Bonwick installed as the gatekeeper • Bonwick granted authority to “rip it out if itʼs broken" — an early BDFL model, and a template for later generations of engineering leadership • Solaris 2.5 shipped on schedule and at quality -
