Scheming French Geeks, Eunuchs OS, Lisping & lots of Guile

I’ve recently installed GuixSD, a distribution of GNU Linux, on one of my machines. GuixSD‖ is notable for having a number of major components (package manager, init system) written in GNU Guile, an implementation of Scheme, which is itself a dialect of Lisp (formerly LISP)†. But Guix is pronounced /ɡiːks/ (i.e. identically to geeks). Why? The final x of Guix is presumably by analogy to Linux, which was itself produced by analogy to Unix‡, based on the first name of its creator, Linus Torvalds.
