I have been working with home=scan and myconfig=scan
So far so good to get my home and config back after rebooting.
But I made a quite long session and now I have no room in home anymore in such a way that I can't even start Knoppix/KDE.

Is there a way to come out of this situation and not losing the data in knoppix.img?
If I boot without home=scan and create another bigger persistent home, can I sort of mount the old knoppix.img and recover the data in there?

BTW I did a search and I apparently didn't find this situation back in earlier posts.
