Do I have to do a guix pull and guix system reconfigure to add a user? I get a "wrong type to apply" error

Guix

Very new here to Guix.

I’m trying to add a user to a clean OS

through creating a config.scm, putting it in /etc/

and then running guix system reconfigure /etc/config.scm

;; This is an operating system configuration template
;; for a minimal setup

(use-modules (gnu))
(use-service-modules networking ssh)
(use-package-modules screen ssh)


(operating-system
  (host-name "bib-baz")
  (timezone "Europe/Brussels")
  (locale "fr_BE.utf8")

  ;; Boot in "legacy" BIOS mode, assuming /dev/sdX is the
  ;; target hard disk, and "my-root" is the label of the target
  ;; root file system.
  (bootloader (bootloader-configuration
                (bootloader grub-bootloader)
                (targets '("/dev/srX"))))
  ;; It's fitting to support the equally bare bones ‘-nographic’
  ;; QEMU option, which also nicely sidesteps forcing QWERTY.
  (kernel-arguments (list "console=ttyS0,115200"))
  (file-systems (cons (file-system
                        (device (file-system-label "GUIX_X86_64-LINUX_1.4.0"))
                        (mount-point "/")
                        (type "ext4"))
                      %base-file-systems))
  
  (users (cons (user-account
                (name "baz")
                (comment "uzaz")
                (group "users")
                (supplementary-groups '("wheel" "netdev")))
               %base-user-accounts))

  ;; Adding base packages
  (packages (append (%base-packages)))

  ;; SSH
  (services (append (list (service dhcpcd-service-type)
                          (service openssh-service-type
                                   (openssh-configuration
                                     (openssh openssh-sans-x)
                                     (port-number 22))))
                          (service loadkeys-service-type "dvorak")
                    %base-services))
)

But I get a failed to load ‘/etc/config.scm' error on /etc/config.scm37:20 Wrong type to apply plus a whole bunch of packages.

What’s going on?

If you change something on the system configuration, you need to rerun guix system reconfigure. A guix pull actualizes the Guix package manager and is not required if you don’t change the system in a way that isn’t dependent on a new Guix feature.

/etc/system.scm isn’t the best location as it’s more user data of the administrator and /etc is part of the system that gets build.

What is at /etc/config.scm37:20 and please post the complete error message.

(packages (append (%base-packages)))

So it has nothing to do with the user.

You can’t append only one list, it requires two or more.
Try only (packages %base-packages).

I think you should use the following format for packages in your os: for example

  (packages (append (list
                     ;; window managers
                     emacs emacs-exwm emacs-desktop-environment
                     ;; terminal emulator
                     xterm)
                    %base-packages))
```

Otherwise, you do not need (append).
