Thanks for reply. I have tried already that you suggested. But the size is still big for my need.
Besides KNOPPIX has 1000 of packages, and I am very confused for which package it breaks the system that I remove.

I need around 70 MB (most size is needed for kernel modules) which will be much less after zip.

I am now remastering the GParted which will be perfect for my needs.
