<title>Command Explanations</title>
<para><command>patch -Np1 -i ../dhcpcd-&dhcpcd-version;-fhs-1.patch</command>:
<application>dhcpcd</application> unpatched puts all configuration
and temporary files in <filename class='directory'>/etc/dhcpc</filename>. This
becomes very annoying when <application>dhcpcd</application> tells you it's
running and it's not. You look in
<filename class="directory">/var/run</filename> for the
<filename>PID</filename> file, but it's not there, the
<filename>PID</filename> file that needs deleting is in
<filename class="directory">/etc/dhcpc</filename>. This patch brings this
program into FHS compliance, but more importantly, puts
files where you expect them to be.</para>
<para><parameter>--prefix=""</parameter>: There may be a good reason for
abandoning the normal BLFS convention of using
<parameter>--prefix=/usr</parameter> here. If you are installing
DHCP, it is likely that it is
required during the boot process and
<filename class="directory">/usr</filename> may be network mounted, in which
case <command>dhcpcd</command> wouldn't be available due to being on the
network! Therefore, depending on your situation, you may want it to be
installed in <filename class="directory">/sbin</filename> or
<filename class="directory">/usr/sbin</filename>. This command installs to
<filename class="directory">/sbin</filename>.</para>
<para><parameter>--sysconfdir=/var/lib</parameter>: This command installs
configuration files in the <filename class="directory">/var/lib</filename>
directory.</para>
<para><parameter>--mandir=/usr/share/man</parameter>: This command installs
the man pages to the <filename class="directory">/usr/share/man</filename>
directory.</para>
