Comment 4 for bug 434181

I'd like to suggest that this rightscale script could be inserted as user-data.

The ubuntu ec2 images support executing arbitrary content passed in via user-data. This hook should be powerful enough to allow the rightscale script to be provided to ec2-init in that user-data and do whatever magic it needs to do.

The benefit of dynamically inserting the script over being hard coded is that there is no need for rightscale to request a ec2-init package upgrade to change their init scripts.

I dont think we have very good doc over how user-data content is handled at the moment, but the implementation is in ec2-run-user-data (http://bazaar.launchpad.net/%7Eubuntu-branches/ubuntu/karmic/ec2-init/karmic/annotate/head%3A/ec2-run-user-data.py) and ec2-init's (http://bazaar.launchpad.net/%7Eubuntu-branches/ubuntu/karmic/ec2-init/karmic/annotate/head%3A/ec2-init) invocation of that.
