try /etc/e-smith/templates/etc/httpd/conf/httpd.conf
There you will see the template fragments.
If you need to make changes, try
mkdir -p /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf
cp whatever fragment from the main directory to the templates-custom directory, make your changes, then
/sbin/e-smith/expand-template /etc/httpd/conf/httpd.conf
service httpd restart
