+# For FRR to work in VyOS as expected we need a few fixups
+#
+# 1. Enable daemons we use in /etc/frr/daemons
+# 2. Set the VRF backend of Zebra to netns (-n option) in /etc/frr/daemons.conf
+#    Otherwise multiple routing tables for PBR won't work
+# 3. Create empty configs for daemons with use
+#    That is to make them possible to start on boot before config is loaded
+#
