title: Can I use double quotes in Chef attribute declaration?
body: <p>I have inherited a cookbook that sets some attributes in the ./attributes/default.rb file as per normal.</p>
  
  <p>However, we have a problem with one of the lines is, which is:</p>
  
  <pre><code>default["obscured"]["mysql"] = "#{node['jboss']['jboss_home']}/modules/com/mysql/jdbc/main"
  </code></pre>
  
  <p>When run, it write this into the node as:</p>
  
  <pre><code>{}/com/mysql/jdbc/main
  </code></pre>
  
  <p>I can confirm that the node['jboss']['jboss_home'] attribute exists and has correct values.</p>
  
  <p>So, I cannot see any problem with the above, except that every other declaration of this type in our cookbooks has single quotes on the attribute to be set (i.e. left side), not double quotes. I haven't heard this of as being an issue before, but I am pretty new to chef.</p>
  
  <p>Is there any rule that says they must be single quotes?</p>
