-If you have keystone enabled, Swift will authenticate against it, make sure to use the keystone URL to auth against.
+   ENABLED_SERVICE="$ENABLED_SERVICES,swift"
 
-At this time Swift is not started in a screen session but as daemon you need to use the **swift-init** CLI to manage the swift daemons.
+If you want a minimal swift install with only swift and keystone you can have this instead in your localrc:
+
+   ENABLED_SERVICES="key,mysql,swift"

+Only swift proxy server is launched in the screen session all other services are started in background and managed by **swift-init* tool.
 
 By default Swift will configure 3 replicas (and one spare) which could be IO intensive on a small vm, if you only want to do some quick testing of the API you can choose to only have one replica by customizing the variable SWIFT_REPLICAS in your localrc.
