K, let me be honest: I haven't heard about demerge before, ever. Interesting and cool! That's still not the same thing though. It's a wrapper around portage for all I can tell and uses portage to get back to some previous (destroyed!) state. Nix doesn't mutate (well, ignoring garbage collects) and provides this out of the box. demerge is a utility that I have to install on top of portage (provided I know about it) and portage itself doesn't know a thing about it. Oh, and it was last touched in 2008. Back to the first line: Good argument though, it _does_ provide rollbacks for portage and - if it still works as advertised and is reliable enough - can simulate a somewhat similar feature, I give you that.
