After playing with the network amanger GUI for a while, and still not
gettign the behavior I wanted (still only the 1'st interface would come
up). I removed the network amnager package, and now the machine behaves as
I desried.

Just putting this in the archive for futire reference.

Is there a command line interface to network amaneger? Is it posible to
edit it's config files by hand. Can it's beahvaior be made non user
centric?
