+# Test UPDATE messages sent by other nodes when the currently authorirative
+# master is unavaialble. The test is performed in the following steps:
+#
+# 1) Master goes down.
+# 2) Slave failover and becomes new master.
+# 3) New master is partitoned away.
+# 4) Old master returns.
+# 5) At this point we expect the old master to turn into a slave ASAP because
+# of the UPDATE messages it will receive from the other nodes when its
+# configuration will be found to be outdated.
