    services: Add hurd-file-systems-service-type.
    
    guix system build ... depends on `file-systems-services'.  Provide a dummy
    for that, so that we can migrate to guix system ...
    
    * gnu/services/hurd.scm (hurd-file-systems-services-shepherd-service,
    hurd-file-systems-services-service-type): New function.
    (hurd-service->shepherd-service): Add entry.
