  <p>and I'd like to get rid of this part:</p>
  
  <pre><code>warning: File listed twice: /etc/mydumpadmin/README.md
  warning: File listed twice: /etc/mydumpadmin/credentials.txt
  warning: File listed twice: /etc/mydumpadmin/mysql-dump.sh
  warning: File listed twice: /etc/mydumpadmin/settings.conf
  </code></pre>
  
  <p>I suppose I have to change something in the spec file, which looks like:</p>
  
  <pre><code>Name:           mydumpadmin

  Release:        0

  <p>but I am not sure exactly what part I should change, to what and why? Please bear with me as this is my first RPM package. Reading documentation now, but sometimes asking questions here on stackoverflow give much clearer and better answers than digging into documentation.</p>
