 That is not quite my user experience.

If you dd the image to the drive you want to install on, upon bootup
disklabel/kernel will incorrectly detect the drive as a 2 mb drive.  You
have to dd some zeroes to the drive, and then reboot, then the image is
gone, etc etc.

So, what i had to do was use the diskettes to install. After that, the ftp
and other sysinst processes worked fine.
