title: Which is the safest way to manage Rails database.yml?
body: <p>Since database.yml file contains some private information, we shouldn't put it under version control. </p>
  
  <p>I just dig out a bunch of solutions for sync database.yml to my server, such as <a href="http://simonecarletti.com/blog/2009/06/capistrano-and-database-yml/" rel="nofollow">this</a>, I just want to know which is the safest way? Do I should only use <code>scp</code> to for that when I use Cap3 deploy?</p>
