  <!-- Jim Fehlig (<jfehlig@novell.com>) suggest the
       following additions to DHCP:

       WRT dhcp element, would it make sense to consider hostname (hostname
       to send to server) and if to change the local hostname to the
       hostname delivered via dhcp?  E.g.  hostname="foo" (default
       `hostname`) sethostname

       Also route:
         setrouting (default "yes")
         setdefaultroute (default "yes")

       and NIS:
         nis (default "yes")
         setnisdomain (default "yes")

       What about dhcpv6?  A separate <dhcp6 /> element?
  -->

  <!-- Jim Fehlig suggest adding static routing info

       As for routing info, how about a separate route element:

       <route gateway="192.168.0.1" /> # destination=default
       <route destination="default" gateway="192.168.0.1" />
       <route destination="10.0.0.0/8" gateway="192.168.0.2" />
       <route destination="2001:DB8:C::/64" gateway="2001:DB8:C::1" />
       <route destination="2001:DB8::/32"> # unrecheable route (loopback)

       It would perhaps make sense to use iproute2 names, that is prefix
       instead of destination and nexthop instead of gateway.
