in repository guix.

commit 689460f82ad0f33253cd2e1b621febf1ed74a402
Author: Ludovic Courtès <ludo@gnu.org>

    services: guix: Depend on 'avahi-daemon' when 'discover?' is set.
    
    Previously, with shepherd 0.10.0, guix-daemon would start quickly,
    possibly before avahi-daemon is running.  Consequently, its "guix
    discover" child process would exit immediately with a warning saying
    "Avahi daemon is not running".
    
    * gnu/services/base.scm (guix-shepherd-service): When DISCOVER? is true,
    add 'avahi-daemon' to 'requirement'.
