I have my doubts about this part of the pre-install script, however my
skills are certainly far inferior to the task of deciphering this:

# way of doing this.  If not, it needs to be figured out and documented to
# avoid confusion.
  use_unix=
  for config in /etc/X11/xorg.conf /etc/X11/XF86Config
/etc/X11/XF86Config-4 ; do
    if [ -f $config ] && grep -q "unix/:" $config &> /dev/null; then
      use_unix=1
    fi
    if [ -f $config ] && grep -q "unix/:-1" $config &> /dev/null; then
      rm -f $config.new $config.rpmsave
      sed "s#unix/:-1#unix/:7100#g" $config > $config.new
      cp -f $config $config.rpmsave
      cat $config.new > $config
      rm -f $config.new
    fi

      cat $config.new > $config

  done

  if [ -n "$use_unix" ] && ! grep -q "no-listen" /etc/X11/fs/config &>

    echo -e "# don't listen on tcp by default\nno-listen = tcp\n" >>

}
