Add comment that you should not have to edit netstart, and if you
do we would like to know about it.

The lo0 interface is now handled just like any other interface,
This makes it possible to do things to it from sysconfig.

Redo the comments in sysconfig about network_interfaces and ifconfig_${X}
to reflect the moving of lo0 to this scheme.  We now have an uncommented
variable for sysintall to find and play with.  (Your welcome Jordan)

Redo the way static routes are handled.  Basically use the same
scheme for routes that I did for network interfaces.  This allows
any number of static routes to be added from sysconfig.

Make sure we do the default route first so we stand a chance of
getting to our DNS server (if we have one) to resolve our own
IP address from $hostname.
