I thought that I can remaster CD after I tried 4 times of my scripts. Each time, it gives me a resonale results after I delete some packages. However, when I starts to do real remastering by installing some packages, then I found that the iso file becomes very big. Here is the result. Before I install ipython package, I got 615 MB iso image. After I install the ipython, I got a 1.225GB image. the size of my knxsource without compression is 1978508. It is smaller than original knoppix source. What I need to do to get a reasonable size of iso.

Thanks
