Hi, I'm enough. Please get me out of this mailing list, thanks a lot!

This is what I have on my local instance that I use day-to-day:
eth0=ndis-bridge,,00:18:8B:26:42:84
eth1=tuntap,,00:18:8B:26:44:80

Every thing is fine with this, reboot and it's still all good.  This 
makes me think it's a mistake to try and set the name and instead the 
real solution is to set a random address.
