I want to add my custom keyboard layout by patching xkeyboard-config so that this layout can be used in the rest of the system configuration.
>From the manual on defining package variants it is clear how to define such a patched variant. However it is not at all clear to me how to use the various package-rewrite options in that manual page to make my system configuration use the patched xkeyboard-config. The only related question (https://lists.gnu.org/archive/html/help-guix/2018-07/msg00008.html) that I have been able to find managed to work around it. As I'm at a loss how to do this cleanly**: could someone give me a pointer on how to adapt the default desktop example (https://guix.gnu.org/manual/en/html_node/Using-the-Configuration-System.html) to add a patched system package such as xkeyboard-config? **) I can see that a work-around is to use a custom guix channel. However that seems a lot of additional work as it would require keeping the channel in sync. There must be a cleaner approach to achieve this.
