<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 <acronym>FHS</acronym> 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 <acronym>BLFS</acronym> convention of using
|
|
<parameter>--prefix=/usr</parameter> here. If you are installing
|
|
<acronym>DHCP</acronym>, 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>
