I get where the post is coming from though. Redox decides to write a brand new kernel with some interesting ideas, but then basically just slaps a UNIX-like userland on top of it.
What's wrong with changing a few things at a time? Why should this project attempt to solve every problem at once? I can't imagine that resulting in a usable system, at least not in the next decade.
Nothing wrong with it really, especially since Redox bills itself as a research OS (at least it did last I checked) and not a contender for replacing desktops.
But I still share the original poster's disappointment in yet another UNIX-like system, especially at a time when, in my opinion, Personal Computing and the Desktop in particular are being driven towards extinction.
If they just waited around for people to support Redox in every application natively, it would never happen. A Posix'y shim layer is a very practical concession.
