OK, this is a proof of concept, but it kinda works.

I created test.xml in the LFS main directory:
-----------------
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN" 
"http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd" [
<!ENTITY script SYSTEM "../bootscripts/lfs/init.d/rc.test">
]>
<article>
<title>Testing</title>

<screen>&script;</screen>

</article>
------------------
I had to process the rc file with:
   sed -e s/\&/\&amp\;/g -e 's/</\&lt\;/' rc > rc.test

to put ampersands and less-than symbols into xml friendly forms.
------------------

I then ran

   xmllint --nonet --noent -o testout.xml test.xml
   xsltproc --nonet stylesheets/lfs-chunked.xsl testout.xml

and it created index.html like I had in mind in my above post.

In other words, we can easily automate including the current bootscripts into an 
appendix.  Adding a new bootscript will require a manual entry of course, but 
that would be only a few lines of xml.

Do you want me to start on adding this to the book as Appendix D?
