how to proceed with chapter 7 concerning cat > output << EOF

If we want to create all files in the book using cat > output << EOF
constructions we have a little problem in chapter 7 - the boot scripts.
Take the first few lines from the rc script:
if we do that in a cat > rc << EOF it will not work properly due to the $ and
in other files the commands includes in ` like kill -9 `cat /var/run/$1.pid`
If you enter them literally, bash will try to execute those. So we have to
escape them. The book will then contain:
cat > rc << EOF
Now $FAILURE will be put in the rc file. But if people choose not to use the
cat command but just copy&paste the content into a file, those backslashes
will become a problem.
So we either can't use the content in the book in a cat > out << EOF
construction and you have copy&paste into vim, or you can do a cat but you
cannot copy&paste into vim.
Although I would much prefer the cat option personally, not everybody will be
happy with it.
A solution could be to create yet another appendix and put the plain scripts
in there without escape sequences (backslashes). Or tell the readers to
download the scripts if they don't want to use the 'cat' construction, but i
rather not do that because it's very limiting.
Opinions and/or alternatives are very welcome
