+// Tests that the creation of a user replicates to secondaries, and survives a restart of all

+// If all data-bearing nodes in a replica set are using an ephemeral storage engine, the set will
+// not be able to survive a scenario where all data-bearing nodes are down simultaneously. In such a
+// scenario, none of the members will have any data, and upon restart will each look for a member to
+// inital sync from, so no primary will be elected. This test induces such a scenario, so cannot be
