; binary logging is required for replication
;log-bin=mysql-bin
+; Normally, a slave does not log to its own binary log any updates that are
+; received from a master server. This option tells the slave to log the updates
+; performed by its SQL thread to its own binary log. For this option to have
+; any effect, the slave must also be started with the --log-bin option to
+; enable binary logging. --log-slave-updates is used when you want to chain
+; replication servers.
