29 | <para><filename>systemd-sysv-generator</filename> is a generator | |
30 | that creates wrapper .service units for | |
31 | <ulink url="https://savannah.nongnu.org/projects/sysvinit">SysV init</ulink> | |
32 | scripts in <filename>/etc/init.d/*</filename> at boot and when | |
33 | configuration of the system manager is reloaded. This will allow | |
34 | <citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry> | |
35 | to support them similarly to native units.</para> | |

38 | in SysV init scripts are interpreted, and the ordering specified | |
39 | in the header is turned into dependencies between the generated | |
a8eaaee7 | 40 | unit and other units. The LSB facilities |
f509443a ZJS |
41 | <literal>$remote_fs</literal>, <literal>$network</literal>, |
42 | <literal>$named</literal>, <literal>$portmap</literal>, | |
43 | <literal>$time</literal> are supported and will be turned into | |
44 | dependencies on specific native systemd targets. See | |
