    <title>Description</title>

    <para><command>systemd-networkd-wait-online</command> is a
    oneshot system service (see <citerefentry><refentrytitle>systemd.service</refentrytitle><manvolnum>5</manvolnum></citerefentry>), that waits for the network to be
    configured. By default, it will wait for all links it is aware of
    and which are managed by
    <citerefentry><refentrytitle>systemd-networkd.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>
    to be fully configured or failed, and for at least one link to
    gain a carrier.</para>

    <title>Options</title>

    <para>The following options are understood:</para>

    <variablelist>
      <varlistentry>
        <term><option>-i</option></term>
        <term><option>--interface=</option></term>

        <listitem><para>Network interface to wait for before deciding
        if the system is online. This is useful when a system has
        several interfaces which will be configured, but a particular
        one is necessary to access some network resources. This option
        may be used more than once to wait for multiple network
        interfaces. When used, all other interfaces are ignored.
        </para></listitem>

      <varlistentry>
        <term><option>--ignore=</option></term>
        <listitem><para>Network interfaces to be ignored when deciding
        if the system is online. By default, only the loopback
        interface is ignored. This option may be used more than once

        <term><option>--timeout=</option></term>
        <listitem><para>Fail the service if the network is not online
