The old domain will not be cleaned up, but will be renamed so a new
-domain can be restarted in it's place. (TODO: what does this mean for
-resources? What is the renamed name?)
+domain can be restarted in it's place. The old domain will be renamed with
+a suffix -1, -2, etc, and assigned a new random UUID; the new domain will
+keep the original name and UUID. The old domain will release the devices that
+it holds, so that the new one may take them.
