Thanks Fredrik!

I really struggle with subtle details that are a few paragraphs 
deep, and so, I am embarassed.

If anyone else is reading this for reference: I should not have 
set =#:user #:t= for =make-forkexec-constructor=. The =#:user= 
keyword expects a string. My user is implicitly when left with the 
default value.

If I may say so, this has been easier to learn than systemd 
services. After many years of mostly failing to use systemd 
properly, I have not yet mastered it.

My user-level services are running :)
