chkconfig only creates or destroys the links between the /etc/rc.d/rcX.d
directories and the actual scripts in /etc/rc.d/init.d.  "off" destroys
the link (if it existed), and "on" creates the link, but that's all.
The service won't start until the next reboot (when the /etc/rc.d/rcX.d
stuff is processed).  "service yum start" starts it immediately (the
same as doing "/etc/rc.d/init.d/yum start").

Yes, that's one way.  Don't forget to do "yum -y update >/dev/null 2>&1"
unless you want mail sent to root everytime it runs.
