   the original problem was the loss of 
the static address we'd put in the 
/etc/network/interfaces file, and our 
subsequent discovery that dhclient3 
was at work. 
   as we got increasingly frustrated, 
we developed the notion that we should 
understand how the box comes up in the 
first place. given that there was an 
init process running and having never 
heard of upstart, my questions were 
posited in terms of init configuration. 
   i've very recently learned to replace 
"init" with "upstart", and i now have a 
few places to go to begin the latest 
round of learning: 


   it's looking more and more that the 
problem with dhclient3 is a bug in 
ubuntu server 8.04.
