Because I still don't think modify-services is documented well enough
and I have only one case where it's working for me, I assume:

As an example,
                   (service openssh-service-type
                            (openssh-configuration
                             (permit-root-login #t)))

Would still work. If it doesn't, I know there is no lint checking for services
in the system config.
