Debconf is being wierd. I use the curses front-end. The current message is this:
Configuring Raidtools2 pump may not work on 2-interface machines Pump has be observed to send packets out of the wrong interface (particularly if Full NAT is enabled in the kernel) and send out packets with a non-0 source address. You may wish to try another dhcp client <==> Now, what's the relationship between raidtools2 and pump? In this case, only that both are being replaced in an apt-get upgrade. -jwb
