Hi,

Julien Lepiller <julien@lepiller.eu> skribis:

> There are different ways to find these values. You can grep through the c=
ode from https://git.savannah.gnu.org/git/guix.git (https://git.savannah.gn=
u.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 did=
n't check). Most of the time however, these variables are explained in the =
manual.

If you use Emacs and Emacs-Guix, you can also run:

  M-x guix-default-services

which is really handy.

Another trick is to run:

  guix system extension-graph /path/to/your/config.scm | dot -Tpdf > t.pdf
  evince t.pdf

to view the =E2=80=9Cservice extension graph=E2=80=9D for your OS configura=
tion.  That
should give you an idea of what=E2=80=99s included and how these bits inter=
act
with one another.

HTH!

Ludo=E2=80=99.
