This commit introduces a custom disk layout different from default configuration offerings by ubiquity/partman, therefore spoofing it in casper stage to dismiss partition setup at earliest possible. Added d-i question dell-recovery/encryption defauled false, toggle it on in the preseed file to enable disk encryption. Custom partition layout fresh added keystore to host all the key files, for instance the key-file for rootfs OS partition. Both the keystore and rootfs partitions are default LUKS encrypted. Initially, 3 key slots are reserved for keystore decryption. The third slot is created only if user decided to adopt measured boot. key slot 0: hardware identity key slot 1: user passphrase key slot 2: random generated fs-unlock firstly finds tpm sealing object if present will retrieve the key according to PCR policy verification on successful will salt chosen PCRs, otherwise simply unlock the rootfs by pre-defined hardware identity.
New added d-i question dell-recovery/use_zfs to enable zfs custom disk layout in the preseed file.
Changes: 1. add zfs-unload-encryption.conf to user-runtime-dir@ systemd 2. add /usr/sbin/zfs-unload-encryption to unload encryption key
