title: Load environment variables in rails app without restarting server
body: <p>How can I make my rails app aware of the new environment variables after I have edited my <code>/etc/environment</code> file on my remote EC2 instance?</p>
  
  <p>I frequently add new (minor) things in my <code>secrets.yml</code> but I don't want to restart my server for it, nor do I want to use an existing secret.</p>
