Anaconda Kickstart %include statements are not working, why ?

Issue

• My kickstart file has a %pre script and %include line to set the timezone, but the installation is pausing and asking me for the timezone, why ?

  install
  reboot
  firstboot --disable
  ...
  %packages
  @core
  
  %pre
  echo "timezone America/Chicago" > /tmp/timezone.txt
  
  %include /tmp/timezone.txt
  
  %post
  ...
