Plug in the bootable Linux CF card and do (as root)
fdisk -l
to see which device path (say /dev/sda, for example).
Then do
dd if=/dev/sda of=/tmp/BootCF.img
to copy the content of CF card into one image file.
Then unplug the CF card and put another CF card, do
dd if=/tmp/BootCF.img of=/dev/sda
to copy back the image file to new CF card.
This is the way to duplicate the bootable CF card
