indeed - now I understand. Right now the Openstack driver uses the
ruby-openstack rubygem [1] (which we co-maintain) to 'talk' to the
Openstack provider. In other words we only consume/interact with the
'native' Openstack (nova/swift/etc) APIs and not with the EC2 API that a
given Openstack provider may expose. This means that even though you are
passing 'user_data' to the server create method in your patch, this will
just be ignored (as the Openstack rubygem and the Openstack API in
general have no idea about 'user_data'). I have to work out the details
around this in order to add what you want - for example use the
appoxy/aws rubygem to talk to the ec2 endpoint of the openstack server.

I opened a JIRA ticket [2] to track this so it doesn't get lost in the
mailing list. Is there an urgency attached to this request (may be a bit
busy with CIMI over the next few days),
