As we supply a default vendor configuration in `/usr/share/defaults/httpd/`, to make modifications to httpd's configuration, you must first create the directory `/etc/httpd/conf.d/`, copy `/usr/share/defaults/httpd/httpd.conf` to `/etc/httpd/conf.d/httpd.conf`, and make modifications to the file in `/etc/httpd/`. If you modify the default vendor configuration instead it will be overwritten with the next update.
