You can use she= pherd and herd commands (without sudo)=2E
For example:
$ shepherd [-c= config=2Escm]
$ herd status

Then configure your `config=2Escm` a= s you like=2E As a default shepherd will use `$XDG_CONFIG_HOME/shepherd/ini= t=2Escm`, and if the variable is not set then `$HOME/=2Econfig/shepherd/ini= t=2Escm`=2E

>It would be awesome if the Guix System could provide= a way to configure these declaratively, too=2E
That can be done by gene= rating a text-file in store containing the desired config then symbolic lin= king it to `$HOME=2Econfig/shepherd/init=2Escm`=2E This all can be done usi= ng guix daemon(declaratively)=2E

Though I am not sure how you can 'a= utostart' the service at boot time and declaratively?

I don't think there's an easy=

you might use the ~/=2Ec=
