Hi Sergiu,
I recently made my redshift configuration using shepherd user
services, which is what people in IRC recommended me.
You can find it here:
https://github.com/ekaitz-zarraga/dotfiles/tree/guix/shepherd/shepherd
Also, it forces me to run the shepherd as a user using my i3 config.
I also wanted to configure it in my config.scm file but people
convinced me not to do so.
I'm not sure why your case shouldn't work though.
Best,
Ekaitz
