I have since found another directive in my "httpd.conf" that i had
overlooked, the directive "<Directory "/var/www/html">" which i found i
needed to also set to "/www/html". Once i changed this, all was well
with either mounting my new "md0" in "/www" or "/var/www" with the
approriate changes in "httpd.conf"
