+
+Introduction
+============
+
+The current Wic implementation supports only the basic kickstart
+partitioning commands: ``partition`` (or ``part`` for short) and
+``bootloader``.
+
+.. note::
+
+   Future updates will implement more commands and options. If you use
+   anything that is not specifically supported, results can be
+   unpredictable.
+
+This chapter provides a reference on the available kickstart commands.
+The information lists the commands, their syntax, and meanings.
+Kickstart commands are based on the Fedora kickstart versions but with
+modifications to reflect Wic capabilities. You can see the original
+documentation for those commands at the following link:
+http://pykickstart.readthedocs.io/en/latest/kickstart-docs.html
+
+Command: part or partition
+==========================
+
+Either of these commands creates a partition on the system and uses the
+following syntax: part [mntpoint] partition [mntpoint] If you do not
+provide mntpoint, Wic creates a partition but does not mount it.
+
+The ``mntpoint`` is where the partition is mounted and must be in one of
+the following forms:
+
+-  ``/path``: For example, "/", "/usr", or "/home"
+
+-  ``swap``: The created partition is used as swap space
+
+Specifying a mntpoint causes the partition to automatically be mounted.
+Wic achieves this by adding entries to the filesystem table (fstab)
+during image generation. In order for Wic to generate a valid fstab, you
+must also provide one of the ``--ondrive``, ``--ondisk``, or
+``--use-uuid`` partition options as part of the command.
+
+.. note::
+
+   The mount program must understand the PARTUUID syntax you use with
+   --use-uuid
+   and non-root
+   mountpoint
+   , including swap. The busybox versions of these application are
+   currently excluded.
+
+Here is an example that uses "/" as the mountpoint. The command uses
+``--ondisk`` to force the partition onto the ``sdb`` disk: part /
+--source rootfs --ondisk sdb --fstype=ext3 --label platform --align 1024
+
+Here is a list that describes other supported options you can use with
+the ``part`` and ``partition`` commands:
+
+-  *``--size``:* The minimum partition size in MBytes. Specify an
+   integer value such as 500. Do not append the number with "MB". You do
+   not need this option if you use ``--source``.
+
+-  *``--fixed-size``:* The exact partition size in MBytes. You cannot
+   specify with ``--size``. An error occurs when assembling the disk
+   image if the partition data is larger than ``--fixed-size``.
+
+-  *``--source``:* This option is a Wic-specific option that names the
+   source of the data that populates the partition. The most common
+   value for this option is "rootfs", but you can use any value that
+   maps to a valid source plugin. For information on the source plugins,
+   see the "`Using the Wic Plugins
+   Interface <&YOCTO_DOCS_DEV_URL;#wic-using-the-wic-plugin-interface>`__"
+   section in the Yocto Project Development Tasks Manual.
+
+   If you use ``--source rootfs``, Wic creates a partition as large as
+   needed and fills it with the contents of the root filesystem pointed
+   to by the ``-r`` command-line option or the equivalent rootfs derived
+   from the ``-e`` command-line option. The filesystem type used to
+   create the partition is driven by the value of the ``--fstype``
+   option specified for the partition. See the entry on ``--fstype``
+   that follows for more information.
+
+   If you use ``--source plugin-name``, Wic creates a partition as large
+   as needed and fills it with the contents of the partition that is
+   generated by the specified plugin name using the data pointed to by
+   the ``-r`` command-line option or the equivalent rootfs derived from
+   the ``-e`` command-line option. Exactly what those contents are and
+   filesystem type used are dependent on the given plugin
+   implementation.
+
+   If you do not use the ``--source`` option, the ``wic`` command
+   creates an empty partition. Consequently, you must use the ``--size``
+   option to specify the size of the empty partition.
+
+-  *``--ondisk`` or ``--ondrive``:* Forces the partition to be created
+   on a particular disk.
+
+-  *``--fstype``:* Sets the file system type for the partition. Valid
+   values are:
+
+   -  ``ext4``
+
+   -  ``ext3``
+
+   -  ``ext2``
+
+   -  ``btrfs``
+
+   -  ``squashfs``
+
+   -  ``swap``
+
+-  *``--fsoptions``:* Specifies a free-form string of options to be used
+   when mounting the filesystem. This string is copied into the
+   ``/etc/fstab`` file of the installed system and should be enclosed in
+   quotes. If not specified, the default string is "defaults".
+
+-  *``--label label``:* Specifies the label to give to the filesystem to
+   be made on the partition. If the given label is already in use by
+   another filesystem, a new label is created for the partition.
+
+-  *``--active``:* Marks the partition as active.
+
+-  *``--align (in KBytes)``:* This option is a Wic-specific option that
+   says to start partitions on boundaries given x KBytes.
+
+-  *``--no-table``:* This option is a Wic-specific option. Using the
+   option reserves space for the partition and causes it to become
+   populated. However, the partition is not added to the partition
+   table.
+
+-  *``--exclude-path``:* This option is a Wic-specific option that
+   excludes the given relative path from the resulting image. This
+   option is only effective with the rootfs source plugin.
+
+-  *``--extra-space``:* This option is a Wic-specific option that adds
+   extra space after the space filled by the content of the partition.
+   The final size can exceed the size specified by the ``--size``
+   option. The default value is 10 Mbytes.
+
+-  *``--overhead-factor``:* This option is a Wic-specific option that
+   multiplies the size of the partition by the option's value. You must
+   supply a value greater than or equal to "1". The default value is
+   "1.3".
+
+-  *``--part-name``:* This option is a Wic-specific option that
+   specifies a name for GPT partitions.
+
+-  *``--part-type``:* This option is a Wic-specific option that
+   specifies the partition type globally unique identifier (GUID) for
+   GPT partitions. You can find the list of partition type GUIDs at
+   ` <http://en.wikipedia.org/wiki/GUID_Partition_Table#Partition_type_GUIDs>`__.
+
+-  *``--use-uuid``:* This option is a Wic-specific option that causes
+   Wic to generate a random GUID for the partition. The generated
+   identifier is used in the bootloader configuration to specify the
+   root partition.
+
+-  *``--uuid``:* This option is a Wic-specific option that specifies the
+   partition UUID.
+
+-  *``--fsuuid``:* This option is a Wic-specific option that specifies
+   the filesystem UUID. You can generate or modify
+   ```WKS_FILE`` <#var-WKS_FILE>`__ with this option if a preconfigured
+   filesystem UUID is added to the kernel command line in the bootloader
+   configuration before you run Wic.
+
+-  *``--system-id``:* This option is a Wic-specific option that
+   specifies the partition system ID, which is a one byte long,
+   hexadecimal parameter with or without the 0x prefix.
+
+-  *``--mkfs-extraopts``:* This option specifies additional options to
+   pass to the ``mkfs`` utility. Some default options for certain
+   filesystems do not take effect. See Wic's help on kickstart (i.e.
+   ``wic help kickstart``).
+
+Command: bootloader
+===================
+
+This command specifies how the bootloader should be configured and
+supports the following options:
+
+.. note::
+
+   Bootloader functionality and boot partitions are implemented by the
+   various
+   --source
+   plugins that implement bootloader functionality. The bootloader
+   command essentially provides a means of modifying bootloader
+   configuration.
+
+-  *``--timeout``:* Specifies the number of seconds before the
+   bootloader times out and boots the default option.
+
+-  *``--append``:* Specifies kernel parameters. These parameters will be
+   added to the syslinux ``APPEND`` or ``grub`` kernel command line.
+
+-  *``--configfile``:* Specifies a user-defined configuration file for
+   the bootloader. You can provide a full pathname for the file or a
+   file that exists in the ``canned-wks`` folder. This option overrides
+   all other bootloader options.
