     <para><filename>systemd-rc-local-generator</filename> is a generator that checks whether
-    <filename>/etc/rc.local</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. Note that the script will be run with slightly different semantics than the original System V
-    version, which was run "last" in the boot process, which is a concept that does not translate to systemd. The
