commit e4e3cb849b51788056888355de5570874c128d46
Author: Marek Paśnikowski <marek@marekpasnikowski.pl>
Date:   Fri Jan 26 11:47:56 2024 +0100

    Turn system-configuration.scm into a proper module

    This fixes the following error:
    (exception misc-error (value #f) (value "no code for module ~S")
      (value ((systems izumi system-configuration))) (value #f))

    Additionaly, the call to load secrets' path is removed, because .guix-channel
    already depends on that directory.

    Turn channels.scm into a proper module

    By doing this and depending on (guix channels), the following error is fixed:
    (exception unbound-variable (value #f) (value "Unbound variable: ~S")
      (value (channel)) (value #f))

commit a50480c8634dab2d6dc97742d489a17bbe51c450
Author: Marek Paśnikowski <marek@marekpasnikowski.pl>
Date:   Fri Jan 26 10:01:44 2024 +0100

    Declare guix repository explicitly

    This fixes the following error message:
    (exception unbound-variable (value #f) (value "Unbound variable: ~S")
      (value (%default-channels)) (value #f))

    On top of that, set channel branch to "wip-channel-2"
