I am no longer able to log into the childhurd vm. My configuration
worked previously and hasn't changed.
            (service hurd-vm-service-type
                     (hurd-vm-configuration
                        (os childhurd-os)
                        (disk-size (* 8 (expt 2 30)))))

(define childhurd-os
       ;; Definition of my GNU/Hurd system, derived from the default one.
       (operating-system
         (inherit %hurd-vm-operating-system)

         ;; Add a user account.
         (users (cons (user-account
                       (name "nathan")
                       (group "users")
                       (password (crypt "password" "$6$abc"))
                       (supplementary-groups '("wheel"))) ;for 'sudo'
                      %base-user-accounts))

         (services
          (modify-services (operating-system-user-services
                            %hurd-vm-operating-system)
            (openssh-service-type
             config => (openssh-configuration
              (inherit config)
              (permit-root-login #t)
              (password-authentication? #t)
))))))
