Can a file be used as a Luks device key?
At least in unsafe places, the file used to unlock the device should be accessible only by the root user, and should be itself stored on an encrypted filesystem, otherwise the encryption becomes useless (is the equivalent of using a big fat lock to protect a door but leaving the key where it can be reached by anyone).
