Multiple NICs and "need net"

What is the "right" way to handle this situation. I have two nic cards
in my laptop. The built-in one and a wireless PCMCIA card. In my
/etc/init.d directory I have:

net.eth0        (10/100BaseT)
net.lo  (loopback)
net.wlan0       (wireless)

On any given boot eth0 or wlan0 will fail since only one of them is
plugged in. However /etc/init.d/netmount has a depend of "need net" and
I would think that either of these being up would suffice, yet it seems
it wants both of them up. IS there a proper way to configure this so
that either on being up meets the needs of "need net"?


Thanks,
