+**Description:** This module provides a way for the user to boot with systemd
+even if the image is set to boot with upstart.  It should be run as one of the
+first cloud_init_modules, and will switch the init system and then issue a

 This should be inert on non-ubuntu systems, and also exit quickly.
 
-config is comes under the top level 'init_switch' dictionary.
+It can be configured with the following option structure::
 
-#cloud-config
-init_switch:
- target: systemd
- reboot: true
+    init_switch:
+      target: systemd (can be 'systemd' or 'upstart')
+      reboot: true (reboot if a change was made, or false to not reboot)
 
-'target' can be 'systemd' or 'upstart'.  Best effort is made, but its possible
-this system will break, and probably won't interact well with any other
-mechanism you've used to switch the init system.

-'reboot': [default=true].
-   true: reboot if a change was made.
-   false: do not reboot.
