Generic module to prepare a flash drive with random data from which a LUKS key file can be derived.
Running the following command from this directory will erase and format
a drive with the partition table specified in cassini.nix:
sudo disko ./cassini.nix --mode zap_create_mount --argstr device <path to device>...where <path to device> is some block device, such as /dev/sdb.
Symlink to the disk configuration module for tatl.
