+SYSV INIT.D SCRIPTS:
+        When calling "systemctl enable/disable/is-enabled" on a unit which is a
+        SysV init.d script, it calls /usr/lib/systemd/systemd-sysv-install;

+        mechanism such as chkconfig or update-rc.d. Packagers need to provide
+        this script if you need this functionality (you don't if you disabled
+        SysV init support).
