Indeed! It works now. Thank you for your Help John !
For this to work though, I just had to correct a typo : add a `comma`
(to _unquote_, if I'm not wrong) before the `(file-append …`.
So, for reference :
----
;; At the top of the file
(use-modules
...
(ice-9 match))
;; Replace %desktop-services with this:
(modify-services %desktop-services
(console-font-service-type configuration =>
(map
(match-lambda
(("tty3" . f)
`("tty3" . ,(file-append
font-terminus
"/share/consolefonts/ter-128n.psf.gz")))
((tty . font) `(,tty . ,font))) configuration)))
