Zbigniew Jędrzejewski-Szmek 11a1589223 tree-wide: drop license boilerplate
Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.

I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.

<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>
<para><filename>systemd-sysv-generator</filename> implements
