-**Summary:** reboot system into another init.
-
-**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
-reboot. The next boot will come up in the target init system and no action will
-be taken.
-
-This should be inert on non-ubuntu systems, and also exit quickly.
-
-It can be configured with the following option structure::
-
-    init_switch:
-      target: systemd (can be 'systemd' or 'upstart')
-      reboot: true (reboot if a change was made, or false to not reboot)
-
-.. note::
-
-    Best effort is made, but it's possible
-    this system will break, and probably won't interact well with any other
-    mechanism you've used to switch the init system.
