ecryptfs-unwrap-passphrase should prompt for "Password for $USER" and not for "passphrase".
Currently it prompts for "passphrase" which is confusing as the user might think that he has to set a new passphrase.
Also, the dialog 'record your encryption passphrase' should state that ecryptfs-unwrap-passphrase should run without sudo.
