<term><parameter>--disable-logger</parameter></term>
<listitem>
<para>This option prevents Inetutils from installing the
<command>logger</command> program, which is used by scripts to
pass messages to the System Log Daemon. Do not install it because
Util-linux installs a more recent version.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><parameter>--disable-whois</parameter></term>
<listitem>
<para>This option disables the building of the Inetutils
<command>whois</command> client, which is out of date. Instructions for
a better <command>whois</command> client are in the BLFS book.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><parameter>--disable-r*</parameter></term>
<listitem>
<para>These parameters disable building obsolete programs that should not
be used due to security issues. The functions provided by these
programs can be provided by the <application>openssh</application>
package in the BLFS book.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><parameter>--disable-servers</parameter></term>
<listitem>
<para>This disables the installation of the various network servers
included as part of the Inetutils package. These servers are deemed not
appropriate in a basic LFS system. Some are insecure by nature and are
only considered safe on trusted networks. Note that
better replacements are available for many of these servers.</para>

<para>One test, <emphasis>libls.sh</emphasis>, is known to fail due to hard
coding of some support program paths. All tests pass if the tests are
rerun at the end of Chapter 6.</para>
