I didn't check setxkbmap when sending the mail, actually its syntax is
the same of ckbcomp.  So you don't have to change the procedure call,
sorry for my misinterpretation.

The keyboard-layout field of operating-system is solely for console
use (used by GRUB, and later loaded via loadkeys when booting).  So
you'll have to pass a  record to the keyboard-layout
field of your xorg-configuration.

In (gnu system keyboard), keyboard-layout is defined as:
--8<---cut here---start->8---
(keyboard-layout name (variant) (#:model) (#:options))
--8<---cut here---end--->8---

So the following should be used instead:
--8<---cut here---start->8---
(keyboard-layout "us" "no" #:options '("grp:switch"))
--8<---cut here---end--->8---


For TTY usage, the  record is used to create a console keymap
via ckbcomp, which has a different syntax from setxkbmap and requires a space
between layout and variant.

And for X, xorg-configuration accepts a  record and sets option
XkbLayout to the name field of that record and XkbVariant to variant (only when
it's present).  Since XkbLayout recognizes the comma syntax and variant is not
set, the result is valid.

So support for  is really environment-specific... But for sway
there's a procedure in rde[1] to create an input configuration as an alist, I
think it can be adapted to create a string as well (I personally use a
mixed-text-file for my sway config[2]).

`package-input-rewriting' (documented in [1]) can be used for the
purpose:

--8<---cut here---start->8---
(map (package-input-rewriting
  `((,emacs-minimal . ,emacs-package)
(,emacs . ,emacs-package)))
 package-list)
--8<---cut here---end--->8---

From the definition in (shepherd support), the location is expected:
--8<---cut here---start->8---
(define %user-log-dir
  ;; Default log directory if shepherd is run as a normal user.
  (string-append (or (getenv "XDG_STATE_HOME")
 (string-append user-homedir "/.local/state"))
 "/shepherd"))
--8<---cut here---end--->8---


And ~/.local/state/log/mcron.log was used before changing to
%user-log-dir:
--8<---cut here---start->8---
#:log-file (string-append
(or (getenv "XDG_STATE_HOME")
(format #f "~a/.local/state"
(getenv "HOME")))
"/log/mcron.log")
--8<---cut here---end--->8---

Seems to be an issue in Shepherd itself, it hung during loading the
configuration.

From my own experience, such issue can be "solved" by rebooting (to
spawn new Shepherd daemons).  I don't know how to debug Shepherd and
there's no enough information for me to find the real cause.

So maybe sending a Shepherd bug report to bug-g...@gnu.org ?

Thanks

If you happen to use the system mcron service as well, please pull to

I don't know much about Shepherd but rebooting seems to be the only
solution when it hangs...

Thank you for reporting the issue!

This is caused by a missing module in mcron's service definition, and
now it should be fixed in 552d0703776c532f25498d5cb852c3c497cb9252.

Please run `guix pull', then reconfigure the home environment.

I have a solution but not about priorities.

The solution depends on how you add packages to your home environment.

If you are referencing them as variables, you can change the variable name of
your package, or directly referencing it with (@ (my test-2) emacs-subed).

If you are using the specification->package procedure, you can change the name
field of your package definition.
