This part of the copyright blurb stems from the GPL use recommendations: https://www.gnu.org/licenses/gpl-howto.en.html The concept appears to originate in times where version control was per file, instead of per tree, and was a way to glue the files together. Ultimately, we nowadays don't live in that world anymore, and this information is entirely useless anyway, as people are very welcome to copy these files into any projects they like, and they shouldn't have to change bits that are part of our copyright header for that. hence, let's just get rid of this old cruft, and shorten our codebase a bit.

<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>
