title: How do I suppress the warning "unable to find the application log" after running "symfony serve"?
body: <p>With Symfony 4.3 and Symfony CLI v4.7.1, when I run:</p>
  
  <pre><code>symfony serve
  </code></pre>
  
  <p>I see the following warning in the output:</p>

    <p>WARNING unable to find the application log</p>
