In this example 'bob' is still a Client module variable. We want to check the old value of bob before restarting the client. And then | |||
* Check the value of bob, to note the old value. Stop the service. Then start client with out own default or old value, and then change the value after started. Client was not started previously. | |||

Unknown: bob | |||
Client not started. | |||
