–> Something very important to remember about partitions
It is important to note that Cylinder 0 contains the disklabel, which
contains the partition table. A normal filesystem can be placed
starting at Cylinder 0, since it will not touch the disklabel.
If you lay down a raw device, for a database, over Cylinder 0,
then you will completely lose all your partitions. You will then
have to restore the disklabel, and backup from tape if you happen to do this.

add resolv.conf entry: domain rabobank.com.au nameserver 192.192.192.252

lesson here is to unplumb interface, and let ifconfig setup the routing.
if you specify an ip address and a netmask it will manage
the routing and the broadcasting.
