I get the same behaviour.

Life for the modern laptop at home :-) Same here.

I have the same question!

It makes no difference (assuming you were in /etc/init.d in the first place).

Not only that, but there's some automagic code in the rc scripts that will try 
to bring the interfaces up without linking it to a soft runlevel. So 
actually, you're better off not doing it.

Actually the message is that net.eth0 is invoking netplug to wait for eth0 in 
the background. I could never work out why that doesn't work with net.eth1.

I guess what we both actually want is for these network dependent services to 
come up when *any* external network interface is functional. But how?
