+ <title>Description</title>
+
+ <para><command>systemd-rc-local-generator</command> is a generator that checks whether
+ <filename>&RC_LOCAL_PATH;</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. The script is run after <filename>network.target</filename>, but in
+ parallel with most other regular system services.</para>
+
+ <para>Note that <filename>rc-local.service</filename> runs with slightly different semantics than the
+ original System V version, which was executed "last" in the boot process, which is a concept that does
+ not translate to systemd.</para>
+
+ <para>Also note that <filename>rc-local.service</filename> is ordered after
+ <filename>network.target</filename>, which does not mean that the network is functional, see
+ <citerefentry><refentrytitle>systemd.special</refentrytitle><manvolnum>7</manvolnum></citerefentry>.
+ 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 at compile time and varies between distributions.</para>
