After starting to become more interested in microkernels&#x2F;exokernels&#x2F;unikernels, I&#x27;ve started wondering if POSIX in all of its glory (and I&#x27;ve always been a huge POSIX fan) is perhaps holding us back from a different and better development model.<p>What I like about this post is that it&#x27;s trying to point out some specific things that are perhaps the most constraining, though I&#x27;m not sure the solutions or conclusions are correct.<p>The question is the right one though.
