Here's what we use to partition a 9GB SCSI disk prior to installation so
that we get the disk layout we want.  The default way that kickstart (disk
druid) did it would put the smallest partitions at the end of the disk.
Not good when you don't want a /boot partition, and / is smaller than your
4GB /usr partition.

We have a different one for use with 18GB systems.  The values you put
into the fdisk command will depend on your hard disk, the type and
geometry.
