flash-knoppix command usage:

$ flash-knoppix --help
Usage: /usr/bin/flash-knoppix [-a] [-f] [-m i|p|n] [-p mb] [image|dir] [target_device]
       -a            Allow fixed disks
       -f            Force overwrite, no questions (batch mode)
       -m i          Method: Create overlay image
       -m p          Method: Create overlay partition (recommended)
       -m n          Method: No overlay (read only)
       -p mb         Overlay partition or image size in MB >= 200
       image.iso     Loopmount source ISO file
       dir           Source data directory containing files

The corresponding window in the flash-knoppix GUI displays the following:

Please select installation method:
p Installation on FAT32 with additional overlay partition.
i Installation on FAT32 with (optional) overlay file [less than 4GB].
n  No Overlay (read-only like CD/DVD).

I've been going with option p, which gives me an installation of the compressed filesystem in /dev/sdb1 (FAT32) and the persistent memory in /dev/sdb2 (ReiserFS).
