If the script requires a configured network connection, it may be desirable to pull in and order it after
<filename>network-online.target</filename> with a drop-in:</para>
<programlisting># /etc/systemd/system/rc-local.service.d/network.conf
[Unit]
Wants=network-online.target
After=network-online.target
</programlisting>
<para>Support for <filename>&RC_LOCAL_PATH;</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.
Note that the path to the script is set a compile time and varies between distributions.</para>
