Re: Problem with a new role

If all you want to do is push the code to that role, I'd suggest using  
deploy:update, instead of a full deploy. The ROLES=import setting on  
the command-line does not mean "only run tasks associated with this  
role", it means "use this role for all tasks". It's not really very  
useful for deployment, as you discovered. It's primary purpose is to  
restrict tasks like "invoke" or "deploy:setup".
