     * **_options_** (list of strings): any additional options to be passed to `cryptsetup luksFormat`.
+    * **_discard_** (boolean): whether to issue discard commands to the underlying block device when blocks are freed. Enabling this improves performance and device longevity on SSDs and space utilization on thinly provisioned SAN devices, but leaks information about which disk blocks contain data. If omitted, it defaults to false.
+    * **_open_options_** (list of strings): any additional options to be passed to `cryptsetup luksOpen`. Supported options will be persistently written to the luks volume.
     * **_wipe_volume_** (boolean): whether or not to wipe the device before volume creation, see [Ignition's documentation on filesystems](https://coreos.github.io/ignition/operator-notes/#filesystem-reuse-semantics) for more information.
     * **_clevis_** (object): describes the clevis configuration for the luks device.
       * **_tang_** (list of objects): describes a tang server. Every server must have a unique `url`.
         * **url** (string): url of the tang server.
         * **thumbprint** (string): thumbprint of a trusted signing key.

       * **_tpm2_** (boolean): whether or not to use a tpm2 device.
       * **_threshold_** (integer): sets the minimum number of pieces required to decrypt the device. Default is 1.
       * **_custom_** (object): overrides the clevis configuration. The `pin` & `config` will be passed directly to `clevis luks bind`. If specified, all other clevis options must be omitted.

     * **_enabled_** (boolean): whether or not the service shall be enabled. When true, the service is enabled. When false, the service is disabled. When omitted, the service is unmodified. In order for this to have any effect, the unit must have an install section.
     * **_mask_** (boolean): whether or not the service shall be masked. When true, the service is masked by symlinking it to `/dev/null`. When false, the service is unmasked by deleting the symlink to `/dev/null` if it exists.

     * **_ssh_authorized_keys_** (list of strings): a list of SSH keys to be added as an SSH key fragment at `.ssh/authorized_keys.d/ignition` in the user's home directory. All SSH keys must be unique.
+    * **_ssh_authorized_keys_local_** (list of strings): a list of local paths to SSH key files, relative to the directory specified by the `--files-dir` command-line argument, to be added as SSH key fragments at `.ssh/authorized_keys.d/ignition` in the user's home directory. All SSH keys must be unique. Each file may contain multiple SSH keys, one per line.
 * **_boot_device_** (object): describes the desired boot device configuration. At least one of `luks` or `mirror` must be specified.
   * **_layout_** (string): the disk layout of the target OS image. Supported values are `aarch64`, `ppc64le`, and `x86_64`. Defaults to `x86_64`.
   * **_luks_** (object): describes the clevis configuration for encrypting the root filesystem.

   * **_mirror_** (object): describes mirroring of the boot disk for fault tolerance.
     * **_devices_** (list of strings): the list of whole-disk devices (not partitions) to include in the disk array, referenced by their absolute path. At least two devices must be specified.
