 The mechanism described here still requires one unencrypted partition to boot from (typically `wd0a`). Full disk encryption would make it more difficult for an attacker to modify the unencrypted part of the disk to plant a backdoor. With only partial encryption, the original [[!template id=man name="cgdconfig" section="8"]] binary may be modified to send the passphrase away, allowing an attacker with a disk dump to recover the data.
