  +--------------------+ Configuring mysql-server-5.5 +---------------------+
  | While not mandatory, it is highly recommended that you set a password   |
  | for the MySQL administrative "root" user.                               |
  |                                                                         |
  | If this field is left blank, the password will not be changed.          |
  |                                                                         |
  | New password for the MySQL "root" user:                                 |
  |                                                                         |

  |                                 <Ok>                                    |
