I'd ftp the sets later as part of the install procedure.

This step only would succeed it the sets are on another partition that
you can leave untouched. Therefore I'd take the sets from ftp. I don't
know if miniroot or sysinst would be the better script to do this.

The rest should be handled by the installation script. There are some
issues that I did not find in the installation document:

 * What can I do or can I not do when I'm running the installation.
   I know what to expect but others might be puzzled.
 * What kind of SCSI mapping is used in the kernel I get the first time. (*)
