While I'll probably not be using this myself, tokhonj's explanation of what this is does make me a bit tickly. Nix as a whole sounds neat. Having that work with LISP/Scheme sounds even neater.
But the name is horrible. Guix makes this sound like something GUI-related. A GNU implementation of X? I don't know. The name is wildly misleading.
They really should consider doing something about that, because naming conventions tend to matter more than you think they do.
I dislike the name too. It's meant to be pronounced "geeks", but I imagine most people will expect to pronounce it "gwicks" or "GUI x" on first look. I'd prefer something like "Gnix", or GNU Nix, which maintains it's origin and makes it clear it's a GNU project. Or just call it "Geeks" if you want it pronounced that way.
