-<p>
-      The <code class="literal">NetworkManager-wait-online</code> service is a <code class="literal">oneshot</code>
-      systemd service that delays reaching the <code class="literal">network-online</code> target until
-      NetworkManager reports that the startup is completed on the D-Bus.
-    </p>
-<p>
-      When the system boots, for example, remote mounts defined in <code class="literal">/etc/fstab</code>,
-      require that the network is up. For this, these systemd units contain the
-      <code class="literal">After=network-online.target</code> setting to order themselves after this
-      target. <code class="literal">NetworkManager-wait-online</code> ensures that the
-      <code class="literal">network-online</code> target is reached only after the network is available.
-    </p>
-<p>
-      Optimally, all services on the host react dynamically to network changes and systemd
-      services do not need to be configured to start after reaching the
-      <code class="literal">network-online</code> target. In this case,
-      <code class="literal">NetworkManager-wait-online.service</code> has no effect and does not delay
-      the boot time. On the other hand, if you encounter a long boot time due to the delay
-      of <code class="literal">NetworkManager-wait-online</code>, investigate the services that require
-      network access and fix them.
-    </p>
-<p>
-      Except for the time out value in the <code class="literal">NetworkManager-wait-online.service</code>
-      unit, you cannot configure this service. Instead, settings in NetworkManager and the
-      connection profiles affect the behavior:
-    </p>
-<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
-<li class="listitem">
-<p>
-          Startup is not complete as long as NetworkManager profiles are in an activating
-	  state. During boot, NetworkManager starts profiles with the
-	  <code class="literal">connection.autoconnect=yes</code> setting. If activation fails,
-	  NetworkManager retries the activation depending on the value of the
-	  <code class="literal">connection.autoconnect-retries</code> setting.
-        </p>
-<p>
-          NetworkManager reports startup complete when all profiles and devices are either
-	  activated or in a disconnect state and no further events are expected.
-        </p>
-</li>
-<li class="listitem">
-<p>
-          When a device reaches the activate state depends on its configuration. For example,
-	  with a profile that has both IPv4 and IPv6 enabled, by default, NetworkManager
-	  considers the device as fully activated already when only one of the address
-	  families is ready.
-        </p>
-<p>
-          The <code class="literal">ipv4.may-fail</code> and <code class="literal">ipv6.may-fail</code> settings
-	  control this behavior. Additionally, the following settings influence when the
-	  two address families complete: <code class="literal">ipv4.required-timeout</code>,
-	  <code class="literal">ipv6.required-timeout</code>, <code class="literal">ipv4.dhcp-timeout</code>,
-	  and <code class="literal">ipv6.ra-timeout</code>. For details, see
-	  <a class="link" href="nm-settings-nmcli.html" title="nm-settings-nmcli"><span class="citerefentry"><span class="refentrytitle">nm-settings-nmcli</span>(5)</span></a>.
-        </p>
-</li>
-<li class="listitem"><p>
-          NetworkManager cannot set IP addresses on bridge and bond devices that have ports
-	  that do not auto-activate. Because of this configuration error,
-	  <code class="literal">NetworkManager-wait-online</code> blocks until the service reaches
-	  its timeout value.
-        </p></li>
-<li class="listitem"><p>
-          Dispatcher scripts for the <code class="literal">pre-up</code> event run at a late stage
-	  during activation of a profile. These scripts block the activation for when
-	  NetworkManager considers the profile fully activated. For details, see
-	  <a class="link" href="NetworkManager-dispatcher.html" title="NetworkManager-dispatcher"><span class="citerefentry"><span class="refentrytitle">NetworkManager-dispatcher</span>(8)</span></a>.
-        </p></li>
-<li class="listitem"><p>
-          The property <code class="literal">connection.wait-activation-delay</code> adds an additional
-	  delay during activation and delays startup complete. This setting works around
-	  certain cases where a device is known to not be ready for a certain amount of time.
-        </p></li>
-<li class="listitem"><p>
-          The property <code class="literal">connection.wait-device-timeout</code> in the connection
-	  profiles cause a delay until the waiting devices appear. This is useful if the
-	  driver takes a longer time to detect the networking interfaces. This setting is
-	  similar to the <code class="literal">connection.gateway-ping-timeout</code> property.
-        </p></li>
-<li class="listitem"><p>
-          With Wi-Fi devices, NetworkManager needs to wait for the first scan result to
-	  know which networks are available. That adds a delay.
-        </p></li>
-<li class="listitem"><p>
-         With Ethernet devices, NetworkManager waits for the carrier until the value in
-	 <code class="literal">[device*].carrier-wait-timeout</code> is reached. This is because some
-	 devices take a long time to detect the carrier. Consequently, booting with cable
-	 unplugged, unnecessarily delays <code class="literal">NetworkManager-wait-online.service</code>.
