Makefile

  ~/.config/guix/channels.scm:
          mkdir -p ~/.config/guix
          cp channels.scm ~/.config/guix/channels.scm

  install:
          guix archive --authorize < signing-key.pub
          guix system reconfigure ./config.scm --substitute-urls='https://ci.guix.gnu.org https://bordeaux.guix.gnu.org https://substitutes.nonguix.org'

System Installation Script

This is to be run after setting up the partitions.

  #!/bin/sh
  herd start cow-store /mnt
  mkdir -p /mnt/etc/guix/
  cp channels.scm /mnt/etc/guix/
  mkdir -p /etc/guix
  cp channels.scm /etc/guix
  guix pull
  sed -i 's|/etc/config.scm|/mnt/etc/config.scm|g' ./config.scm
  guix system init ./config.scm /mnt --substitute-urls="https://ci.guix.gnu.org https://bordeaux.guix.gnu.org https://substitutes.nonguix.org"

Configuration Definitions

File System

The variable %local-filesystem extracts the file system definitions from the installer-provided config.scm file.

  (define %local-filesystem
    (call-with-input-file "/etc/config.scm"
      (lambda (port)
        (read port)
        (read port)
        (eval (cadar (last-pair (read port)))
              (interaction-environment)))))

As a sibling to the former, the variable %local-swap does the same with the swap partition.

  (define %local-swap
    (call-with-input-file "/etc/config.scm"
      (lambda (port)
        (read port)
        (read port)
        (let* ((os-list (read port))
               (os-list-length (length os-list)))
          (eval
           (cadr
            (list-ref os-list
                      (- os-list-length 2)))
           (interaction-environment))))))

Channels

This adds the Nonguix channel.

  ;; Copy this to ~/.config/guix/channels.scm.
  (cons* (channel
        (name 'nonguix)
        (url "https://gitlab.com/nonguix/nonguix")
        ;; Enable signature verification:
        (introduction
         (make-channel-introduction
          "897c1a470da759236cc11798f4e0a5f7d4d59fbc"
          (openpgp-fingerprint
           "2A39 3FFF 68F4 EF7A 3D29  12AF 6F51 20A0 22FB B2D5"))))
       %default-channels)

Services

Simple Services

These services are unmodified, or have just few settings.

Service	Options
tlp	()
thermald	((adaptive? #t))
bluetooth	()
earlyoom	((minimum-available-memory 5) (minimum-free-swap 5))
inputattach	()
libvirt	((unix-sock-group "libvirt"))
fstrim	()
fprintd	()

Modified Desktop Services

  (public-key (ecc (curve Ed25519) (q #C1FD53E5D4CE971933EC50C9F307AE2171A2D3B52C804642A7A35F84F3A4EA98#)))

Greeter Service

greetd is a broken mess, yet here we are.

  (service greetd-service-type
           (greetd-configuration
            (greeter-supplementary-groups
             (list "video" "input"))
            (terminals
             (list
              (greetd-terminal-configuration
               (terminal-vt "1"))
              (greetd-terminal-configuration
               (terminal-vt "2"))
              (greetd-terminal-configuration
               (terminal-vt "3"))
              (greetd-terminal-configuration
               (terminal-vt "4"))
              #;(greetd-terminal-configuration
              (terminal-vt "7")
              (terminal-switch #t)
              (default-session-command
              (greetd-wlgreet-session
              (command
              (file-append swayfx "/bin/sway")))))
              (greetd-terminal-configuration
               (terminal-vt "8"))))))

Screen Locker Service

For some reason, this service runs on root level for Guix.

  (service screen-locker-service-type
           (screen-locker-configuration
            (name "swaylock")
            (program
             (file-append swaylock-effects "/bin/swaylock"))
            (using-setuid? #f)))

Operating System
