# Matching with "Type=ether" causes issues with containers because it also matches virtual Ethernet interfaces (veth*).
# See https://bugs.archlinux.org/task/70892

# systemd-networkd does not set per-interface-type default route metrics

# Explicitly set route metric, so that Ethernet is preferred over Wi-Fi and Wi-Fi is preferred over mobile broadband.
# Use values from NetworkManager. From nm_device_get_route_metric_default in
