+ <title>Description</title>
+
+ <para><filename>systemd-sysv-generator</filename> is a generator
+ that creates wrapper .service units for
+ <ulink url="https://savannah.nongnu.org/projects/sysvinit">SysV init</ulink>
+ scripts in <filename>/etc/init.d/*</filename> at boot and when
+ configuration of the system manager is reloaded. This will allow
+ <citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+ to support them similarly to native units.</para>
+
+ <para><ulink url="http://refspecs.linuxbase.org/LSB_3.1.1/LSB-Core-generic/LSB-Core-generic/iniscrptact.html">LSB headers</ulink>
+ in SysV init scripts are interpreted, and the ordering specified
+ in the header is turned into dependencies between the generated
+ unit and other units. The LSB facilities
+ <literal>$remote_fs</literal>, <literal>$network</literal>,
+ <literal>$named</literal>, <literal>$portmap</literal>,
+ <literal>$time</literal> are supported and will be turned into
+ dependencies on specific native systemd targets. See
+ <citerefentry><refentrytitle>systemd.special</refentrytitle><manvolnum>5</manvolnum></citerefentry>
+ for more details.</para>
+
+ <para>SysV runlevels have corresponding systemd targets
+ (<filename>runlevel<replaceable>X</replaceable>.target</filename>).
+ The wrapper unit that is generated will be wanted by those targets
+ which correspond to runlevels for which the script is
+ enabled.</para>
+
+ <para><command>systemd</command> does not support SysV scripts as
+ part of early boot, so all wrapper units are ordered after
+ <filename>basic.target</filename>.</para>
