They don't differ: 'root' is just another service, as 'nginx' is. Our
'reload' action can handle many arguments as well. The only tiny
difference is that the 'root' service is implemented by Shepherd, not by
Guix.

Sure, I updated the documentation. I had forgotten the "Shepherd
Services" part and I think it helps understanding. But I didn't talk
about the 'root' service because it is a Shepherd thing and is already
described in the Shepherd manual.
WDYT?
