We'd have to look in all the possible folders, and there may (and due
to 99-deafult.link, always will) be files there, so we don't really
have a reasonable test. When we start shipping some default .network
files it becomes even harder (e.g. the thing Lennart mentioned which
will only apply for given interfaces that we create ourselves inside
systemd-nspawn). We'll then always have config files, but they may not
necessarily apply (and we can't know whether or not they ever will).

Cheers,
