>Description:
adding a "tap0"-interface to "network_interfaces" or "cloned_interfaces" in 
"/etc/rc.conf" results in this message repeated two times during system startup:
  "ifconfig: interface tap0 does not exist"

"device tap" is in kernel-configuration, "openvpn" can open and utilize "tap0"
without any problems.

i use "/etc/start_if.tap0" as a workaround:
 $ cat /etc/start_if.tap0 
 #!/bin/sh
 echo 1 > /dev/tap0

for me this is important since "named" couldn't bind to that interface/ip 
otherwise, by the time "openvpn" allocates it "named" has already dropped 
priviliges (running as user "bind")
