<para><filename>systemd-sysv-generator</filename> is a generator that creates wrapper .service units for

|
<ulink url="https://savannah.nongnu.org/projects/sysvinit">System V init</ulink> scripts in
|
|
<filename>/etc/init.d/*</filename> at boot and when configuration of the system manager is reloaded. This
|
|
allows <citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry> to
|
|
support them similarly to native units.</para>
