+# We cannot use the legacy 'netconfig' task because with MOS 9, it won't create
+# the proper dependency on the 'virtual_ips' task for the InfluxDB-Grafana
+# nodes. As a consequence, the deployment will fail because the nodes will
+# perform operations that download stuff from the Internet (like running
+# 'apt-get update') while the virtual router isn't ready yet. For MOS 8, the
+# task depends on the 'tools' task and not on the 'virtual_ips' task otherwise
+# it creates a dependency cycle. In this case, this isn't an issue because the
+# default gateway is only changed at post-deployment (see the
+# 'influxdb-configure-default-route' task).
