CreateUser Difficulty

So I've been having trouble getting create user to work correctly, or I'm missing it is but I'm missing something really obvious. Is it simply that I configure it how I want it and place the package in the custom pkg folder within InstaDMG? If thats the case, the problem I'm having is after imaging the machine, unlike instaUser the image boots up like its a fresh install of mac osx and wants owner information filled out again? Its a minor detail yes, but i want to avoid it because this image is going to be mass distributed. New to all of this Any help would be greatly appreciated
