    services: virtual-build-machine: Disable substitutes by default.
    
    These are useless when offloading yet were causing problems on systems
    where the default substitute servers are unreachable.
    
    * gnu/services/virtualization.scm (%virtual-build-machine-operating-system):
    Add ‘use-substitutes?’ field to ‘guix-configuration’.
