I recently cut a 5.1.1 Knoppix DVD and I think I have the same problem, I only get an option to save to floppy from the Knoppix save config dialog - not very helpful as I don't have the floppy connected in my Laptop. At v4.0 of Knoppix DVD I also had an option for /mnt/sda1 (my USB Memory stick). I can actually load my config from v4.0 into v5.1.1 which allowed me to take over my wireless network settings, but I can't save any updated config to the drive under 5.1.1 because it doesn't appear as an option. I tried mounting sda1 first and changing the write mode to write enable - I can save files to the USB stick with other utilities/apps etc. (e.g. Open Office docs, etc.)
Is there a method of getting /mnt/sda1 to appear in the options for saving the config or is there a command line alternative where I can specify /mnt/sda1 in the command line arguments?
Thanks.
