# The user can explicitly set host variables "network_provider",

# Usually, the user only wants to select the "network_provider"

# internal variable "{{ network_provider_current }}". Hence,
# depending on the "network_provider", a different set of
# service-name and packages is chosen.

# from "network_service_name_default_*" and "network_packages_default_*"
# apply. These values are hard-coded in this file, but they also could
