+#
+# We can not easily restart the first node, so instead we restart all the other nodes. MTR does not allow multiple nodes
+# to be down at the same time, so restarts are sequential.
+#
+# We can not test any of the actual WAN optimizations from inside MTR and no 
+# status variables are provided. So we only check that simple replication works.
