I'm confused, was your comment meant to be sarcastic? It didn't read that way to me at all. If not, then I don't get the "Captain Obvious" reply, as I simply answered the implied question that was the foundation of your comment ("Why is it named 'PlayNixOS' if it isn't based on Nix/NixOS?"). Your comment did not indicate to me that this was knowledge you already had, so I don't see a point in calling me out on it. There are plenty of people using a Linux-based operating system that don't know the history of it, so I can't simply assume every commenter has that knowledge.
