My take on this is that in the future it will be possible to construct Noux environments such that autotools can be run in Noux to produce a native Noux build (and maybe cross-compiling), but the practical thing to do will be to try to and fool existing autotools tests, and only inside Noux.
I do think that Nix can trick autotools into building on Noux, but first Noux needs to be faster and I want to find out how far merging file systems can go before hitting the point of diminishing returns.

Yes, I want to create an alternate layer for dependencies and locating the required makefiles.

You might be right, sometimes I think that Nix is a bit heavyweight for simply generating text files like it often does, but I don't know much about Guile. As far as porting Guix, it might look like a good idea to try and make it work on top of Noux, but my experience with Nix was that to fix every required unix-ism will take more time and in the end you will loose some important potential features. It may be possible to reuse my Nix libraries for Guix, but I made some changes that break compabality with upstream Nix for the sake of security and content addressing, which you might not agree with. The build controller component I have actually contains no 'Nix' code or libraries, so if Guix can produce the some low-level build recipe files, that would deduplicate a lot of work. Cheers, Emery
