51<para><application>Fcron</application> uses the cron facility of
52<command>syslog</command>
53to log all messages. Since <acronym>LFS</acronym> does not set up this
54facility in <filename>/etc/syslog.conf</filename>, it needs to be done
55prior to installing <application>Fcron</application>. This command will append
56the necessary line to the current <filename>/etc/syslog.conf</filename>:</para>
57<screen><userinput><command>cat &gt;&gt; /etc/syslog.conf &lt;&lt; "EOF"
58# Begin fcron addition to /etc/syslog.conf

88will use an iinstalled <acronym>MTA</acronym> to email you the results of the
89<command>fcron</command> script. If you wish to utilize this feature, change
90the switch to <parameter>--with-sendmail=<replaceable>[path to your
91MTA]</replaceable> </parameter>.</para>
92
93<para><parameter>--with-answer-all=no</parameter>: After the files are
94installed, the <command>make install</command> script enters into a
95configuration routine. The first test will be whether to install a boot script in the <filename class="directory">/etc/rc.d/init.d</filename> directory with
96the appropriate symbolic links in run levels 2, 3, 4, and 5. The second is to
97stop any current fcron processes and start a new one. Since this is probably
98your first install and we want a boot script based upon the
99<acronym>BLFS</acronym> template, we answer 'n' to both tests.</para>
