If you ask folks like Brian Kernighan and Rob Pike, they will tell you all the unicorns are dead on Linux because everything is _not_ a file. The only safe harbor for the unicorns are Plan9 and now Inferno. Plan9 and Inferno carry on the original Unix philosophy of "everything is a file." What you call a directory does not matter because the unicorns were nearly extinct already. <https://en.wikipedia.org/wiki/Plan_9_from_Bell_Labs> and <https://en.wikipedia.org/wiki/Inferno_(operating_system)>.
