<title>Installation of Sysvinit</title>

<para>When runlevels are changed (for example, when halting the system),
<command>init</command> sends termination signals to those processes that it
itself started and that shouldn't be running in the new runlevel. While doing
this, <command>init</command> outputs messages like "Sending processes the TERM
signal" which seem to imply that it is sending these signals to all currently
running processes. To avoid this misinterpretation, you can modify the source
so that these messages read like "Sending processes started by init the TERM
signal" instead:</para>

<screen><userinput>cp src/init.c{,.backup}
sed 's/Sending processes/&amp; started by init/g' \
&nbsp;&nbsp;&nbsp;&nbsp;src/init.c.backup &gt; src/init.c</userinput></screen>

<para>Compile Sysvinit:</para>

<screen><userinput>make -C src</userinput></screen>

<para>And install it:</para>

<screen><userinput>make -C src install</userinput></screen>
