<para>When run levels are changed (for example when going to shutdown
the system) the init program is going to send the TERM and KILL signals
to all the processes that init started. But init prints a message to the 
screen saying "sending all processes the TERM signal" and the same for the 
KILL signal. This implies that init sends this signal to all the currently 
running processes, which isn't the case. To avoid this confusion, you
change the init.c file so that the sentence reads "sending all 
processes started by init the TERM signal" by running the following
commands. If you don't want to change it, skip it.</para>

<para><screen><userinput>cp src/init.c src/init.c.backup &amp;&amp;
sed 's/\(.*\)\(Sending processes\)\(.*\)/\1\2 started by init\3/' \

mv tmp~ src/init.c</userinput></screen></para>
