Context English Chinese (Simplified) (zh_CN) State
With configuration settings, it is possible to configure options passed to both the <_:buildtarget-1/> and <_:buildtarget-2/> stages of the <application>NanoBSD</application> build process, as well as internal options passed to the main build process of <application>NanoBSD</application>. Through these options it is possible to cut the system down, so it will fit on as little as 64MB. You can use the configuration options to trim down FreeBSD even more, until it will consists of just the kernel and two or three files in the userland. 通过对配置进行设置， 可以配置用以传递给 <application>NanoBSD</application> 构建过程中 <_:buildtarget-1/> 和 <_:buildtarget-2/> 阶段的联编和安装选项， 以及 <application>NanoBSD</application> 的主构建过程中的选项。 通过使用这些选项可以削减系统的尺寸， 使之能够放入 64MB 的存储。 您还可以进一步通过这些选项来削减 FreeBSD， 直到它只包含内核以及两三个用户环境文件为止。
The configuration file consists of configuration options, which override the default values. The most important directives are: 配置文件中包含用以代替默认值的配置选项。 最重要的语句包括：
<literal>NANO_NAME</literal> — Name of build (used to construct the workdir names). <literal>NANO_NAME</literal> ── 本次构建的名称 (用于创建工作目录的名字)。
<literal>NANO_SRC</literal> — Path to the source tree used to build the image. <literal>NANO_SRC</literal> ── 用以联编和构建映像的源码树的位置。
<literal>NANO_KERNEL</literal> — Name of kernel configuration file used to build kernel. <literal>NANO_KERNEL</literal> ── 用以联编内核的配置文件的名字。
<literal>CONF_BUILD</literal> — Options passed to the <_:buildtarget-1/> stage of the build. <literal>CONF_BUILD</literal> ── 用于传递给 <_:buildtarget-1/> 构建阶段的选项。
<literal>CONF_INSTALL</literal> — Options passed to the <_:buildtarget-1/> stage of the build. <literal>CONF_INSTALL</literal> ── 用于传递给 <_:buildtarget-1/> 构建阶段的选项。
<literal>CONF_WORLD</literal> — Options passed to both the <_:buildtarget-1/> and the <_:buildtarget-2/> stage of the build. <literal>CONF_WORLD</literal> ── 用以传递给 <_:buildtarget-1/> 和 <_:buildtarget-2/> 这两个构建阶段的选项。
<literal>FlashDevice</literal> — Defines what type of media to use. Check <filename>FlashDevice.sub</filename> for more details. <literal>FlashDevice</literal> ── 定义所用的介质类型。 要了解进一步的细节， 请参考 <filename>FlashDevice.sub</filename> 文件。
Custom Functions 功能定制
It is possible to fine-tune <application>NanoBSD</application> using shell functions in the configuration file. The following example illustrates the basic model of custom functions: 通过在配置文件中使用 shell 函数可以进一步微调 <application>NanoBSD</application>。 下面的例子展示了定制函数的基本模式：
cust_foo () (
echo "bar=baz" &gt; \
${NANO_WORLDDIR}/etc/foo
)
customize_cmd cust_foo 		cust_foo () (
echo "bar=baz" &gt; \
${NANO_WORLDDIR}/etc/foo
)
customize_cmd cust_foo
A more useful example of a customization function is the following, which changes the default size of the <filename>/etc</filename> directory from 5MB to 30MB: 下面是一个更贴近实际的例子， 它将默认的 <filename>/etc</filename> 目录尺寸， 从 5MB 调整为 30MB：
cust_etc_size () (
cd ${NANO_WORLDDIR}/conf
echo 30000 &gt; default/etc/md_size
)
customize_cmd cust_etc_size 		cust_etc_size () (
cd ${NANO_WORLDDIR}/conf
echo 30000 &gt; default/etc/md_size
)
customize_cmd cust_etc_size
There are a few default pre-defined customization functions ready for use: 除此之外， 还有几个默认的预定义定制函数：
<literal>cust_comconsole</literal> — Disables <citerefentry><refentrytitle>getty</refentrytitle><manvolnum>8</manvolnum></citerefentry> on the VGA devices (the <filename>/dev/ttyv*</filename> device nodes) and enables the use of the COM1 serial port as the system console. <literal>cust_comconsole</literal> ── 在 VGA 设备上禁止 <citerefentry><refentrytitle>getty</refentrytitle><manvolnum>8</manvolnum></citerefentry> (<filename>/dev/ttyv*</filename> 设备节点) 并启用串口 COM1 作为系统控制台。
<literal>cust_allow_ssh_root</literal> — Allow <systemitem class="username">root</systemitem> to login via <citerefentry><refentrytitle>sshd</refentrytitle><manvolnum>8</manvolnum></citerefentry>. <literal>cust_allow_ssh_root</literal> ── 允许 <systemitem class="username">root</systemitem> 通过 <citerefentry><refentrytitle>sshd</refentrytitle><manvolnum>8</manvolnum></citerefentry> 登录。
<literal>cust_install_files</literal> — Installs files from the <filename>nanobsd/Files</filename> directory, which contains some useful scripts for system administration. <literal>cust_install_files</literal> ── 从 <filename>nanobsd/Files</filename> 目录中安装文件， 这包含一些实用的系统管理脚本。
Adding Packages 安装预编译软件包
Packages can be added to a <application>NanoBSD</application> image using a custom function. The following function will install all the packages located in <filename>/usr/src/tools/tools/nanobsd/packages</filename>: 通过增加自定义的函数， 可以在 <application>NanoBSD</application> 增加预编译的软件包。 下面的函数会添加位于 <filename>/usr/src/tools/tools/nanobsd/packages</filename> 的全部预编译软件包：
install_packages () (
mkdir -p ${NANO_WORLDDIR}/packages
cp /usr/src/tools/tools/nanobsd/packages/* ${NANO_WORLDDIR}/packages
cp $(which pkg-static) ${NANO_WORLDDIR}/
chroot ${NANO_WORLDDIR} sh -c 'cd packages; /pkg-static add *;cd ..;'
rm -rf ${NANO_WORLDDIR}/packages ${NANO_WORLDDIR}/pkg-static
)
customize_cmd install_packages 		install_packages () (
mkdir -p ${NANO_WORLDDIR}/packages
cp /usr/src/tools/tools/nanobsd/packages/* ${NANO_WORLDDIR}/packages
cp $(which pkg-static) ${NANO_WORLDDIR}/
chroot ${NANO_WORLDDIR} sh -c 'cd packages; /pkg-static add *;cd ..;'
rm -rf ${NANO_WORLDDIR}/packages ${NANO_WORLDDIR}/pkg-static
)
customize_cmd install_packages

Updating NanoBSD 更新 NanoBSD
The update process of <application>NanoBSD</application> is relatively simple: 更新 <application>NanoBSD</application> 相对而言较为简单：
Build a new <application>NanoBSD</application> image, as usual. 和之前一样构建新的 <application>NanoBSD</application> 映像文件。
Upload the new image into an unused partition of a running <application>NanoBSD</application> appliance. 将新的映像放入正运行的 <application>NanoBSD</application> 设备中的一个未用的分区。
The most important difference of this step from the initial <application>NanoBSD</application> installation is that now instead of using <filename>_.disk.full</filename> (which contains an image of the entire disk), the <filename>_.disk.image</filename> image is installed (which contains an image of a single system partition). 与之前最初安装 <application>NanoBSD</application> 的步骤相比， 这一步骤最重要的区别在于这次不应使用 <filename>_.disk.full</filename> 文件 (它包含整个盘的映像)， 而应安装 <filename>_.disk.image</filename> 映像 (这个文件中， 只包含一个系统分区)。
Reboot, and start the system from the newly installed partition. 重新启动， 并从新安装的分区中启动系统。
If all goes well, the upgrade is finished. 如果一切顺利的话， 升级工作就完成了。
