When I read these howto's
http://fedoraproject.org/wiki/Openvpn
http://library.linode.com/networking/openvpn/centos-5
on setting up an OpenVPN server, I see that only the last of the two have the step
. /etc/openvpn/easy-rsa/2.0/build-key-server server
Should that step also have been in the Fedora howto, or is it not required?
