    <title>Description</title>

    <para><filename>repart.d/*.conf</filename> files describe basic properties of partitions of block
    devices of the local system. They may be used to declare types, names and sizes of partitions that shall
    exist. The
    <citerefentry><refentrytitle>systemd-repart</refentrytitle><manvolnum>8</manvolnum></citerefentry>
    service reads these files and attempts to add new partitions currently missing and enlarge existing
    partitions according to these definitions. Operation is generally incremental, i.e. when applied, what
    exists already is left intact, and partitions are never shrunk, moved or deleted.</para>

    <para>These definition files are useful for implementing operating system images that are prepared and
    delivered with minimally sized images (for example lacking any state or swap partitions), and which on
    first boot automatically take possession of any remaining disk space following a few basic rules.</para>

    <para>Currently, support for partition definition files is only implemented for GPT partitition
    tables.</para>

    <para>Partition files are generally matched against any partitions already existing on disk in a simple
    algorithm: the partition files are sorted by their filename (ignoring the directory prefix), and then
    compared in order against existing partitions matching the same partition type UUID. Specifically, the
    first existing partition with a specific partition type UUID is assigned the first definition file with
    the same partition type UUID, and the second existing partition with a specific type UUID the second
    partition file with the same type UUID, and so on. Any left-over partition files that have no matching
    existing partition are assumed to define new partition that shall be created. Such partitions are
    appended to the end of the partition table, in the order defined by their names utilizing the first
    partition slot greater than the highest slot number currently in use. Any existing partitions that have
    no matching partition file are left as they are.</para>

    <para>Note that these definitions may only be used to created and initialize new partitions or grow
    existing ones. In the latter case it will not grow the contained files systems however; separate
    mechanisms, such as
    <citerefentry><refentrytitle>systemd-growfs</refentrytitle><manvolnum>8</manvolnum></citerefentry> may be
    used to grow the file systems inside of these partitions.</para>

        previous size of the partition (in case the partition already exists) is also enforced as lower bound
        for the new size. The values should be specified as multiples of 4096 bytes, and are rounded upwards
        (in case of <varname>SizeMinBytes=</varname>) or downwards (in case of
        <varname>SizeMaxBytes=</varname>) otherwise. If the backing device does not provide enough space to
        fulfill the constraints placing the partition will fail. For partitions that shall be created,
        depending on the setting of <varname>Priority=</varname> (see above) the partition might be dropped
        and the placing algorithm restarted. By default a minimum size constraint of 10M and no maximum size
        constraint is set.</para></listitem>

        <varname>SizeMaxBytes=</varname>, except that unlike partition sizes free space can be shrunk and can

        <listitem><para>Takes a path to a regular file, block device node or directory. If specified and the
        partition is newly created the data from the specified path is written to the newly created
        partition, on the block level. If a directory is specified the backing block device of the file
        system the directory is on is determined and the data read directly from that. This option is useful
        to efficiently replicate existing file systems on the block level on a new partition, for example to
        build a simple OS installer or OS image builder.</para>

        <para>The file specified here must have a size that is a multiple of the basic block size 512 and not
        be empty. If this option is used, the size allocation algorithm is slightly altered: the partition is
        created as least as big as required to fit the data in, i.e. the data size is an additional minimum
        size value taken into consideration for the allocation algorithm, similar to and in addition to the
        <varname>SizeMin=</varname> value configured above.</para>

        <para>This option has no effect if the partition it is declared for already exists, i.e. existing
        data is never overwritten. Note that the data is copied in before the partition table is updated,
        i.e. before the partition actually is persistently created. This provides robustness: it is
        guaranteed that the partition either doesn't exist or exists fully populated; it is not possible that
        the partition exists but is not or only partially populated.</para>

        specified and the partition is newly created it is formatted with the specified file system (or as
        swap device). The file system UUID and label are automatically derived from the partition UUID and
        label. If this option is used, the size allocation algorithm is slightly altered: the partition is

        <para>Similar to the behaviour of <varname>CopyBlocks=</varname> the file system is formatted before

        a source file or directory on the host, the second path refers to a target in the file system of the
        newly created partition and formatted file system. This setting may be used to copy files or
        directories from the host into the file system that is created due to the <varname>Format=</varname>
        option. If <varname>CopyFiles=</varname> is used without <varname>Format=</varname> specified
        explicitly, <literal>Format=</literal> with a suitable default is implied (currently
        <literal>ext4</literal>, but this may change in the future). This option may be used multiple times
        to copy multiple files or directories from host into the newly formatted file system. The colon and
        second path may be omitted in which case the source path is also used as the target path (relative to
        the root of the newly created file system). If the source path refers to a directory it is copied
        recursively.</para>

        <para>This option has no effect if the partition already exists: it cannot be used to copy additional

      <para>The home partition gets all available disk space while the swap partition gets 1G at most and 64M
      at least. We set a priority > 0 on the swap partition to ensure the swap partition is not used if not

      <title>Create B partitions in an A/B Verity setup, if missing</title>

      <para>Let's say the vendor intends to update OS images in an A/B setup, i.e. with two root partitions
      (and two matching Verity partitions) that shall be used alternatingly during upgrades. To minimize
      image sizes the original image is shipped only with one root and one Verity partition (the "A" set),
      and the second root and Verity partitions (the "B" set) shall be created on first boot on the free
      space on the medium.</para>
