[Bug 461156] [NEW] User data is not base64 decoded before being presented to the instance

[Markus Lindenberg]

Public bug reported:

User data supplied using "euca-run-instances --user-data-file" is not decoded before being presented to the instance. 
Inside the instance, "curl http://169.254.169.254/latest/user-data" should fetch the decoded user data, whereas eucalyptus will return a base64 and url encoded string. This breaks ec2-run-user-data from the ec2-init package, rendering instance configuration using the user-data mechanism unusable. 

EC2 documentation at http://docs.amazonwebservices.com/AWSEC2/2007-03-01/DeveloperGuide/AESDG-chapter-instancedata.html states that EC2 will return decoded data (i don't have a ec2 account so i can't confirm this):
"The user data must be base64-encoded before being submitted to the API. The API command-line tools perform the base64-encoding for you. The data will be base64 decoded before being presented to the instance."
