| <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>7</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> |
