I got a new laptop so I made a Makefile to install all the scheme implementations that I need ~retropikzel/r7rs-scheme-installer - sourcehut git , also works inside docker.
I though somebody else might find it usefull too. It works with defaults on guix too, just needs dependencies. For example Sagittarius is nice Scheme implementation that unfortunately does not have Guix package yet. I think STklos might be missing too currently.
Alpine and Fedora support are as of now work in progress.
