Public bug reported:

To replicate, attempt to pass in the example script from the doc here:

http://cloudinit.readthedocs.io/en/latest/topics/format.html#user-data-
script

with base64 encoding.

I tried using the AWS-SDK for Ruby V2 with a very simple base64 encoded
script (which worked fine in trusty), and the sample script from above
in the AWS EC2 console's launch-instance wizard (which looks like it's
also doing base64 encoding behind the scenes).

Attached are log files from passing the documentation's sample script
into an Ubuntu 16.04 EC2 instance (ami-40d28157) by pasting the script
into the user-data textbox of the launch instance wizard (which seems to
do base64 encoding).

Evidence it failed to run: 
  -There was no /root/output.txt,
  -"Hello World" is nowhere in "/var/log/cloud-init-output.log"
