I have a 2 Gb SD Chip of Knoppix 6.2.1 that works just about right.
My portable has a hard drive, a cdrw drive and a usb slot for
one-and-one-only SD Chip. I also have another physically identical
2 Gb SD Chip.

I'd like to end up with a second 2 Gb Chip identical to the first.
I don't want to go to all the trouble of re-mastering. Isn't there
some (simpler) way to utilize the capabilities I've indicated to
get what I want? Utilizing dd, toram and other majic words, perhaps?
