<section id='openembedded-kickstart-wks-reference'> + <title>Introduction</title> + + <para> + The current Wic implementation supports only the basic kickstart + partitioning commands: + <filename>partition</filename> (or <filename>part</filename> + for short) and <filename>bootloader</filename>. + <note> + Future updates will implement more commands and options. + If you use anything that is not specifically supported, results + can be unpredictable. + </note> + </para> + + <para> + 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: + <literallayout class='monospaced'> + <ulink url='http://pykickstart.readthedocs.io/en/latest/kickstart-docs.html'>http://pykickstart.readthedocs.io/en/latest/kickstart-docs.html</ulink> + </literallayout> + </para> + </section> + + <section id='command-part-or-partition'> + <title>Command: part or partition</title> + + <para> + Either of these commands creates a partition on the system and uses + the following syntax: + <literallayout class='monospaced'> + part [<replaceable>mntpoint</replaceable>] + partition [<replaceable>mntpoint</replaceable>] + </literallayout> + If you do not provide <replaceable>mntpoint</replaceable>, Wic + creates a partition but does not mount it. + </para> + + <para> + The <filename><replaceable>mntpoint</replaceable></filename> is + where the partition is mounted and must be in one of the + following forms: + <itemizedlist> + <listitem><para> + <filename>/<replaceable>path</replaceable></filename>: + For example, "/", "/usr", or "/home" + </para></listitem> + <listitem><para> + <filename>swap</filename>: + The created partition is used as swap space + </para></listitem> + </itemizedlist> + </para> + + <para> + Specifying a <replaceable>mntpoint</replaceable> 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 <filename>--ondrive</filename>, + <filename>--ondisk</filename>, or + <filename>--use-uuid</filename> partition options as part of the + command. + <note> + The mount program must understand the PARTUUID syntax you use + with <filename>--use-uuid</filename> and non-root + <replaceable>mountpoint</replaceable>, including swap. + The busybox versions of these application are currently + excluded. + </note> + Here is an example that uses "/" as the + <replaceable>mountpoint</replaceable>. + The command uses <filename>--ondisk</filename> to force the + partition onto the + <filename>sdb</filename> disk: + <literallayout class='monospaced'> + part / --source rootfs --ondisk sdb --fstype=ext3 --label platform --align 1024 + </literallayout> + </para> + + <para> + Here is a list that describes other supported options you can use + with the <filename>part</filename> and + <filename>partition</filename> commands: + <itemizedlist> + <listitem><para> + <emphasis><filename>--size</filename>:</emphasis> + 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
