Do you want this to be mounted on boot?  I don’t think there’s a way to
express that a mount should happen after the network has come up (yet).

You can only tell Guix not to try to mount the disk on boot.  Use
auto-mounting to mount the disk on demand at a later point.  (We don’t
have a service for autofs yet.)

Your contributions in this area would be welcome!

There is no module “(gnu packages zsh)”.  “zsh” is now in “(gnu packages
shells)”.

Here’s what I do in my config:

--8<---------------cut here---------------start------------->8---
(define dvorak-evdev
  (call-with-input-file "/etc/config.d/evdev.conf" read-string))

[…]

(operating-system …
  (services …
    (modify-services %desktop-services
      (slim-service-type
       config => (slim-configuration
                  (inherit config)
                  (startx (xorg-start-command
                           #:configuration-file
                           (xorg-configuration-file
                            #:extra-config
                            (list dvorak-evdev))))))
                            …)))
--8<---------------cut here---------------end--------------->8---

You can use something like that to add to the xorg configuration file.
Just put your snippet in a file and slurp it up.

Not sure about this one.  Your config looks okay to me.  I’m not using
this myself, so I don’t know if there’s a bug in our documentation.

Don’t know about this one.  Is any kernel firmware loading mechanism
involved or do you suspect an xorg configuration problem?
