    <title>Description</title>

    <para><filename>systemd-rc-local-generator</filename> is a generator that checks whether
    <filename>/etc/rc.local</filename> exists and is executable, and if it is pulls the
    <filename>rc-local.service</filename> unit into the boot process. This unit is responsible for running this script
    during late boot. Note that the script will be run with slightly different semantics than the original System V
    version, which was run "last" in the boot process, which is a concept that does not translate to systemd. The
    script is run after <filename>network.target</filename>, but in parallel with most other regular system
    services.</para>

    <para>Support for <filename>/etc/rc.local</filename> is provided
    for compatibility with specific System V systems only. However, it is strongly recommended to avoid making use of
    this script today, and instead provide proper unit files with appropriate dependencies for any scripts to run
    during the boot process.</para>
