4<para>When run levels are changed (for example when going to shutdown
5the system) the init program is going to send the TERM and KILL signals
6to all the processes that init started. But init prints a message to the
7screen saying "sending all processes the TERM signal" and the same for the
8KILL signal. This implies that init sends this signal to all the currently
9running processes, which isn't the case. To avoid this confusion, we
10change the init.c file so that the sentence reads "sending all
11processes started by init the TERM signal".</para>
