rcorder - wait for tap0

[Per olof Ljungmark]

Despite large amounts of cofee and time I cannot grasp how to make this 
happen.

What I want is

Boot -> start openvpn/tap0 configured -> start named -> start jails

Because the jails uses tap0 of course they cannot start before tap0 is 
up, but this is what happens in the default configuration.

Surely this cannot be unique? How did you do it?

Preferrably without messing with rc.d scripts that gets overwritten when 
updated.

Thanks!
