I really enjoyed this talk[1] by Bryan Cantrill, part of which is about what it took to emulate Linux&#x27;s syscalls from within SmartOS. It&#x27;s lengthy, but enjoyable.<p>One of the applications that they tried to port directly to before the emulation layer was htop, and he has a good rant about what that took because of its use of &#x2F;proc and how that made porting it very difficult.<p>Given that, I&#x27;m sure this wasn&#x27;t easy. Kudos!<p>[1] <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=TrfD3pC0VSs" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=TrfD3pC0VSs</a>
