[guix-commits]

janneke pushed a commit to branch wip-hurd-vm
in repository guix.

commit efad7e08c6e3595b20ab81b5b20e890dae34810c
Author: Jan (janneke) Nieuwenhuizen <address@hidden>
AuthorDate: Mon Apr 13 11:04:09 2020 +0200

    services: Add hurd-user-services-service-type.
    
    The `guix-daemon' service type depends on `user-services'.  Provide a dummy
    for that, so that we can use the guix-daemon service unmodified.
    
    * gnu/services/hurd.scm (hurd-user-services-shepherd-service,
    hurd-user-services-service-type): New function.
    (hurd-service->shepherd-service): Add entry.
