With Knoppix 4.0.2 I am no longer able to do this. I have tried creating a "knoppix.img" file and typing
home=scan
home=/dev/sda1
home=/dev/sda1/knoppix.img
home=/mnt/sda1
home=/mnt/sda1/knoppix.img
but none of them work. What am I doing wrong? How can I trouble-shoot?

3. tried to mount my Lexar usb drive where I keep my install goodies. Wouldn't mount .... DMESG showed SDA1 now called UBA1..... why ???
This is due to a linux kernel change. The very brain of the OS, the Linux kernel version 2.6.x, the internal architechture has changed and this has resulted in USB devices mapped to /dev/uba. Yes this is frustrating but going forward, this may be a permanent change. It is more logical to have USB devices at a /dev/uba1 as opposed to /dev/sda1 because /dev/sd? was created years ago for SCSI devices.
This change occured in the time between Knoppix 3.7 & 3.8.x and the change is in Knoppix 3.8.x & up.
Try using home=/dev/uba1

I hope this helps.
