 #   state transfer

+#   accepted
+#   Note that rsync 3.10 is incompatible with Percona XtraDB 5.5
+#   currently (see launchpad bug #1315528). xtrabackup-v2 is the
+#   recommended solution when using Percona XtraDB on platforms such as
+#   Ubuntu trusty which provide rsync 3.10

 # [*root_password*]
 #   (optional) The mysql root password.
