> You were literally wrong given the context of the conversation. It is immaterial which features Solaris got 13 years down the road in its competition with Linux. No, you were wrong with the statement "This also glosses over that commercial Unices weren't superior technology.". The context was Linux killing off the (technically superior) competition, a process that took decades. There are many other technologies that Solaris had years before Linux, e.g. decent SMP, Zones (containers), ZMF management and many other features that Linux still does not have. QNX had realtime features and a microkernel. > I figure in your mind it has to do something with micro-architecture rather than vendors not giving a flying fart, so I'll bite. The situation is more complex than "vendors not giving a flying fart". Linux does not have a stable module ABI, in fact, it doesn't even guarantee a stable API. This is all part of "kernel architecture" and highly relevant. Regarding microkernels, security concerns will eventually force this design on future operating systems (e.g. Google's Fuschia)
