+# The configuration for redis instances is expected to be named same as   #
+# port the instance will be running on. For example if redis should       #
+# listen on 6379, there should be a configuration file in                 #
+# /etc/redis/6379.conf. Generic settings can be put in                    #
+# /etc/redis/redis.conf and included in other configurations. s6 instance #
+# name should be the port number as well, 6379 in this case.              #
