Because I am a Guix Noob, that's my first attempt to modify some guix
stuff and also while I am good with elisp I am not experienced with
Guile, but yes mostly it's about me beeing a guix noob, also that would
enable me to have a notebook with a good guix environment, have not even
really good access to the emacs guix tools which makes development even
more difficult.
That seemed the best quick / dirty way, that I have to update my eudev
package each update upstream and that that sucks I know and such
solution would then the next step, but if you can give me the code for
it I would be very happy :)
