Re: two factor authentication with zuluCrypt

This will work, but it is not really 2-factor, as the key-file will 
not be "something you have". In fact, "something stored on disk" is
already done by LUKS, in the form of the salts and the key.

If you store part of the passphrase on an USB-Key, that may be
borderline 2-factor, but I doubt it really increases security.
