+# one of three authentication methods:

+# 2. specifying the user and password in the handler config,
+#    which generates a temporary .my.cnf in /root/.my.cnf
+# 3. specify the config file with --defaults-file
+#    (this option DOESN'T WORK WITH MYSQLHOTCOPY)

- # because then anyone would be able to see it with a 'ps aux'. instead, we create a
