TODO

- check all the gateways that might have been defined for a given interface:          * dump netstat -nr, parse, and arping the gateways

- create if-up.d/down scripts to test for issues in network setup
   TODO:
      - if we have a DNS server in our same subnet try to test it too (but how
	do we do this? Maybe with  ipsc or prips ? )
		We could use 'ipsc -i eth0 -c' to obtain the CIDR block
		and 'prips <CIDR>' to find if its there
      - Make it possible to test server availability in a generic manner
        and warn if a given server is not reachable
        ( have a file with servers to test for when the interface's UPs?)
   DONE:
      - link status
      - arping of IP address to find if someone has our own IP


DONE
----

- move network-test from debian-goodies to here

- have the package make it possible to setup default routes for interfaces
  easily (through a script) and avoid the issues described in 
  #368228
