Then just another comment: If you use <%if ... -%> and <% end -%> than these statements will not produce blank lines in your final file... To your actual problem: What happens if you just put a <%= dns_role %> in front of your if-statement. Are you sure dns_role is actual set to the correct value (no hidden blanks or anything)? If dns_role is correctly set but your if-statement is still not evaluated try with dns_role.to_s to make sure its a string. Or maybe there is syntax error, missing bracket or whatever in your template (or node manifest that mixes up scope) -Stefan
