knoppix configuration save, and installing ddd via rpm ???

Hi there all,

I got a hold of Knoppix last night, and are very impressed... but, am having two issues with it.

1. I save KNOPPIX configuration to hda1, but when I restart, I can not get the saved configuration to return.

2. I downloaded the lastest data display debugger from the debian web site. When I used rpm, I got the message "dpkg: unable to access dpkg status area : Read only file system

I understand that a cd is a read only file system, so how do I install this program and make it last through the configuration settings? Is it possible, or will I need to do a partition and install linux etc....
