#2 server-id would make replication setup easier

If the my.sandbox.cnf files had server-id in them, it would make it less confusing to setup replication between sandboxes, should that be desired. As it is the CHANGE MASTER TO command succeeds and eventually START SLAVE just says "server is not configured as slave" even though SHOW SLAVE STATUS seems correct. The server-id is the only thing missing to make this work easily.
