Makefile

  reconfigure:
	mkdir -p ~/.config/guix
	cp channels.scm ~/.config/guix/channels.scm
	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
  set euxo -pipefail

  mkdir -p /mnt/boot/efi
  mount /dev/disk/by-label/EFI /mnt/boot/efi
  herd start cow-store /mnt
  guix pull -C./channels.scm

  hash guix
  guix system -L. init config.scm /mnt --substitute-urls="https://ci.guix.gnu.org https://bordeaux.guix.gnu.org https://substitutes.nonguix.org"

                          (device (file-system-label "EFI"))

Channels

This adds the Nonguix channel.

  (cons* (channel
          (name 'nonguix)
          (url "https://gitlab.com/nonguix/nonguix")

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	()

Unattended Upgrade Service

  (service unattended-upgrade-service-type
   (unattended-upgrade-configuration
    (schedule "5 12 * * 1")
    #;(channels
     <<root-channels>>)))

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)))
