Philip Henslowe: Mr. Fennyman, allow me to explain about the theatre business. 
The natural condition is one of insurmountable obstacles on the road to imminent disaster. 

Hugh Fennyman: So what do we do? 

Philip Henslowe: Nothing. Strangely enough, it all turns out well. 

Hugh Fennyman: How? 

Philip Henslowe: I don't know. It's a mystery.

"""

Juju fails to update addresses in relations when those addresses
change.  This script can be used to propagate address changes on a
unit to all of its relations and related units.

This is a workaround for http://pad.lv/1215579

You need to transfer this file to all the units with changed addresses

Placement
---------

Deployer supports flexible per unit placement policies. A unit placement policy allows for
specifying which machine a unit is placed on, including allowing multiple units to be deployed
 to the same machine.

This is expressed in deployer config via the ‘to’ list parameter on a service. Each unit that
needs placement must have its placement specified individually else the default behavior is used,
per the service’s constraints.
