I think the approach in this script is overall reasonable, but one thing
I prefer about the current /etc/rc.d/defaultroute is that it doesn't
need to be configured with a specific IP address, so it can "just work"
out of the box.

Jeremy, was your primary motivation for netwait DHCP, or are there other
bootup issues you had to address with it as well?

What do you think about combining the two, so that we'd have the current
functionality if DHCP is in use and netwait_ip is not set, and the ping
check if netwait_ip is set (regardless of the DHCP setting)?

I think "netwait" is a more descriptive name than "defaultroute."
