(Get the code!)
While implementing the GCE provider for Juju we found that the metadata API breaks when trying to retrieve certain binary formats. In our case the gz of user-data. The API only streams out the first 5 bytes, encounters what it preceives as a EOF/nil character and truncates the rest of the request.
We've opened an issue with Google directly, but in the meantime a work around is to allow an explicit encoding to be set for the user-data field of the GCE metadata. This will allow use to base64 encode the binary blob, which the API returns the entire contents of without issue.
