55 | <title>Description</title> | |
56 | ||
57 | <para><filename>systemd-sysv-generator</filename> is a generator | |
58 | that creates wrapper .service units for | |
59 | <ulink url="https://savannah.nongnu.org/projects/sysvinit">SysV init</ulink> | |
60 | scripts in <filename>/etc/init.d/*</filename> at boot and when | |
61 | configuration of the system manager is reloaded. This will allow | |
62 | <citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry> | |
63 | to support them similarly to native units.</para> | |

65 | <para><ulink url="http://refspecs.linuxbase.org/LSB_3.1.1/LSB-Core-generic/LSB-Core-generic/iniscrptact.html">LSB headers</ulink> | |
66 | in SysV init scripts are interpreted, and the ordering specified | |
67 | in the header is turned into dependencies between the generated | |
a8eaaee7 | 68 | unit and other units. The LSB facilities |
f509443a ZJS |
69 | <literal>$remote_fs</literal>, <literal>$network</literal>, |
70 | <literal>$named</literal>, <literal>$portmap</literal>, | |
71 | <literal>$time</literal> are supported and will be turned into | |
72 | dependencies on specific native systemd targets. See | |
73 | <citerefentry><refentrytitle>systemd.special</refentrytitle><manvolnum>5</manvolnum></citerefentry> | |
74 | for more details.</para> | |

76 | <para>SysV runlevels have corresponding systemd targets | |
77 | (<filename>runlevel<replaceable>X</replaceable>.target</filename>). | |
a8eaaee7 | 78 | The wrapper unit that is generated will be wanted by those targets |

79 | which correspond to runlevels for which the script is |

219e0ea7 | 82 | <para><command>systemd</command> does not support SysV scripts as |
f509443a ZJS |
83 | part of early boot, so all wrapper units are ordered after |
