title: %include centos kickstart unable to open input kickstart file
body: <p>Hi would like to have multiple kickstart files which use a central kickstart file for the bulk of the install and a second file for the small differences. I'm building DVDs for distribution.</p>
  
  <p>The first ks contains small config and has a %include line which points to a common ks file which should do most of the work.</p>
  
  <p>I'm having trouble with %include line.</p>
  
  <p>Fist of all have I understood what %include is for?
  Second I think I have the syntax wrong because when I boot I get the following error message:</p>
  
  <pre><code>unable to open input kickstart file: Could not open/read file:///mnt/sysimage/media/dvd/ks/common.cfg
  </code></pre>
  
  <p>I am installing from a DVD what is the correct path or syntax to the files stored in a sub directory called /ks/ of the DVD's root?</p>
  
  <p>I have tried the following:</p>
  
  <pre><code>%include /mnt/sysimage/media/dvd/ks/common.cfg
  %include cdrom:/ks/common.cfg 
  </code></pre>
  
  <p>Does anyone have any working examples?</p>
  
  <p>Thanks in advance for your support</p>
