          <filename class="directory">/bin</filename> instead of
          <filename class="directory">/usr/bin</filename>. This is the
          correct location according to the FHS, because some of the Psmisc
          binaries are used by the CLFS-Bootscripts package.</para>

    <para os="h">There is no reason for the <command>pstree</command> and

    <para os="j">By default, Psmisc's <command>pidof</command> program is not installed.
    This usually is not a problem because it is installed later in the Sysvinit
    package, which provides a better <command>pidof</command> program. If
    Sysvinit will not be used for a particular system, complete the installation
    of Psmisc by creating the following symlink:</para>

<screen os="k" role="nodump"><userinput>ln -sv killall ${CLFS}/bin/pidof</userinput></screen>
