  Hi Guixers,

  (define myself (guix-noob-user (not (programmer))))

  Trying to change console font with the following in "services" section
of my system configuration file :

----
…
  (services (append (list
        …
        (service console-font-service-type
          `(("tty3" . ,(file-append font-terminus "/share/consolefonts/ter-128n"))))
      ) %desktop-services))
…
----

which results in the following error when reconfiguring the system :

----
$ sudo guix system --dry-run reconfigure /etc/config.scm
guix system: error: service 'console-font-tty3' provided more than once
----

  I probably missunderstand something and/or ill-format the
configuration…?… Help appreciated.

  Below is the related [(guix) Base services] Texinfo section.

----
--scheme Variable: console-font-service-type
    Install the given fonts on the specified ttys (fonts are per
    virtual console on the kernel Linux).  The value of this service is
    a list of tty/font pairs.  The font can be the name of a font
    provided by the ‘kbd’ package or any valid argument to ‘setfont’,
    as in this example:
      `(("tty1" . "LatGrkCyr-8x16")
        ("tty2" . ,(file-append
                      font-tamzen
                      "/share/kbd/consolefonts/TamzenForPowerline10x20.psf"))
        ("tty3" . ,(file-append
                      font-terminus
                      "/share/consolefonts/ter-132n"))) ; for HDPI

This is because there is already a console-font-service-type in
%desktop-services. You will need to modify the existing service instead
like below. Note I have not tested this myself but something like it can be
found in the documentation of guile association lists

https://www.gnu.org/software/guile/manual/html_node/Adding-or-Setting-Alist-Entries.html

;; 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")))
        ((tty . font) `(,tty . ,font)))
      configuration)))

No problem. The error message is saying that such a service would
conflict with the existing one. The aim of the snippet is to keep the
other tty fonts and update the one on tty3.

Hope that helps!

  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 :

          `("tty3" . ,(file-append

                        "/share/consolefonts/ter-128n.psf.gz")))
        ((tty . font) `(,tty . ,font))) configuration)))

Ah, good catch. HTH!
