When you use an IDE CDROM, you can use an empty configuration media. During the bootup Devil-Linux will offer you to copy the standard configuration onto it.
if further configuration adjustments must be done, e.g. :
root password (by default, no password is set)
public and private key generated when sshd is run for the first time the new configuration can easily be saved on the configuraiton media by calling the save-config script
don't forget to set write protection on the configuration media
