Thanks Garrett.  This helps me alot.  I've always thought this was wrong
but didn't fully understand what was going on so I wasn't sure.  It also
explains why the system hangs (waits for timeout) when you enable NIS and 
try to boot.  

I've always just hacked the IP # into those lines in sysconfig but wondered
if I was incorrect in doing so.

What is the `route_loopback' trying to do anyhow?
