Howdy,

It’s a bit overkill indeed… but I like it.  :-)

Julien: could you move the DNS code to a new module, say (guix dns), and
then add the Knot test?

(So first patch adds (guix dns), second patch adds the test.)

In passing, for (guix dns) it would be nice if you could add docstrings
as you see fit, and attempt to use full words in identifiers (“address”
rather than “addr”, “resolve” rather than “resolv”, etc.¹).

This looks really nice, thanks for working on it!
