<para>There is no reason for the <command>pstree</command> and

|
<command>pstree.x11</command> programs to reside in <filename

|
class="directory">/bin</filename>. Therefore, move them to <filename
|
|
class="directory">/usr/bin</filename>. Also, there is no need for
|
|
<command>pstree.x11</command> to exist as a separate program. Make it
|
|
a symbolic link to <command>pstree</command> instead:</para>
|
|
|

<screen><userinput>mv /bin/pstree* /usr/bin
|
|
ln -sf pstree /usr/bin/pstree.x11</userinput></screen>
|
|
|
|
<para>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><userinput>ln -s killall /bin/pidof</userinput></screen>
