ubuntu_init_switch: reboot system into another init
This 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.
config is comes under the top level 'init_switch' dictionary.
#cloud-config
init_switch:
target: systemd
'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.
