Completely agreed - If I ask nova to do something for me as an end user, I
expect it either to be completed in its entirety or not at all.

If we just log and error and move on, end users can no longer rely on that
file injection having completed successfully. Say a user has an image that
uses the injected file to determine the correct server role
and provision itself, they now need to to something equivalent to "wait for
the instance to boot, ssh in, and check the file exists".
