Hi,

There are different ways to find these values. You can grep through the code 
from https://git.savannah.gnu.org/git/guix.git 
(https://git.savannah.gnu.org/cgit/guix.git for the web version). You can also 
run `guix repl` and type the variable name (you might need to import some 
modules before, I didn't check). Most of the time however, these variables are 
explained in the manual.

For %desktop-services, the actual definition is around here: 
https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/services/desktop.scm#n1047

For default values of records, you'll have look at the code or the manual. 
Services are defined in gnu/services/*.scm.
