Hi,

The persistent home image is stored as a regular img file and so can be mounted as a loop device.

The steps below is an example of a persistent home image stored as /media/hdb1/knoppix.img. I am also assuming what you want to copy are data files from the old persistent home image.

1. Start Knoppix but do not load the persistent home image. So, don't enter home=scan, and if prompted by Knoppix to load an image, just say cancel.
2. Mount the partition where the image is stored: in this case /media/hdb1. Make it writable.
3. Rename /media/hdb1/knoppix.img to some other name like test.img.
4. Open a shell and enter the following codes:
Code:
mkdir /media/image
mount /media/hdb1/test.img /media/image -o loop=/dev/loop3
5. The contents of your old persistant image are now viewable under the folder /media/image. For example the stuff on the old desktop is found at /media/image/home/knoppix/Desktop.
6. Create a new persistent home image of larger size.
7. Copy over whatever you want from /media/image to the home folder or desktop or wherever you want. These will now be part of the new persistant home image.
8. Umount /media/image.

It worked for me, so I hope it works for you. Regards.
