If you're doing any kind of shell scripting, get to know and love
#raw. It makes life a lot easier, especially if your shell scripts
aren't using cobbler variables. Even then, there are ways to get
around that:
#set foo = $getVar('foo','foo was not set by cobbler')
export FOO=$foo
#raw
echo $FOO
#end raw
This is really useful, for example if you have shell script generating
other scripts in %post (ie. firstboot/rc.local stuff) so you don't
have to do stuff like \\\$variable all the time. The
keep_ssh_host_keys snippet that ships with cobbler shows a snippet
that is completely wrapped by #raw/#end raw, since it doesn't require
any access to cobbler variables to function.
