    <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>

        <term><option>--interface=</option><replaceable>INTERFACE</replaceable><optional>:<replaceable>OPERSTATE</replaceable></optional></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.
        Optinally, required minimum operational state can be
        specified after a colon <literal>:</literal>. Please see
        <citerefentry><refentrytitle>networkctl</refentrytitle><manvolnum>1</manvolnum></citerefentry>
        for possible operational states. If the operational state is not specified here, then
        the value from <varname>RequiredForOnline=</varname> in the corresponding
        <filename>.network</filename> file is used if present, and <literal>degraded</literal> otherwise.
