Thank you very much for your effort in explaining the following. Much
appreciated ☺

Hmm. The other one (below) seems straight forward and simpler. 😉 Thank
s though. :)

Thanks a lot again! Would you be able to add this definition
(%nitrokey-udev-rule) into master udev definitions in guix? So that any
user who wants to use these rules now or in future, can just modify
%desktop-services and append %nitrokey-udev-rule, as you suggested
below. ☺

Gonna try ☺

Ah I see. 😕
