    130   <para>The <command>login</command>, <command>agetty</command>, and
    131   <command>init</command> programs (and others) use a number of log
    132   files to record information such as who was logged into the system and
    133   when. However, these programs will not write to the log files if they
    134   do not already exist. Initialize the log files and give them
    135   proper permissions:</para>
