> New operating systems today tend to be just ways of reimplementing Unix. If they have a novel architecture -- and some do -- the first thing to build is the Unix emulation layer. > How can operating systems research be relevant when the resulting operating systems are all indistinguishable? > There was a claim in the late 1970s and early 1980s that Unix had killed operating systems research because no one would try anything else. At the time, I didn’t believe it. Today, I grudgingly accept that the claim may be true (Microsoft notwithstanding). > A victim of its own success: portability led to ubiquity. That meant architecture didn’t matter, so now there’s only one. Linux is the hot new thing... but it’s just another Unix. http://herpolhode.com/rob/utah2000.pdf http://herpolhode.com/rob/utah2000.pdf
