fusecompress on knoppix-data.img?

Exactly what I'm going to try.
I think that could be achieved by mounting knoppix-data.img read only, create a new ramdisk about the same size as knoppix-data.img and mount it read-write over /KNOPPIX-DATA. Then everytime you run a certain script or shutdown knoppix-data.img get's remounted read-write and all changes are copied over to knoppix-data.img...

To bad I'm not good enough
First I'm going to try and make fusecompress work, then I'll play around with the ramdisk stuff

You surely describe the easy way, but my knoppix-data.img is 4GB...
So in my case, there must be some extracting and updating of selected directories involved.
