  This hook allows for multiple encrypted root devices
  (for example, root and swap) to be opened at init time.
  It uses a kernel argument cryptkey= in same way as the encrypt
  hook (it can be left empty, or supplied as dev:fstype:path,
  or supplied as dev:raw_numeric_offset:length).
  Instead of the encrypt hook's required cryptdevice= argument,
  it instead uses a cryptdevices= argument, whose format must be:

    cryptdevices=dev_holding_keyfiles:fstype[:path],\\
        dev1_to_decrypt:alias_for_it,\\
        dev2_to_decrypt:alias_for_it,...
