Ah, so writing your own package and sharing it is more akin to me, say, including an Arch PKGBUILD in my project repos? Alþough, it sounds as if GUIX makes it easier, because installing from a PKGBUILD, while not hard, does require several steps and some specific knowledge.

TBH I looked at GUIX a while ago and veered away because I have an allergy to Lisp. I am fond of Lisp, I just don't like it.
