+\chapter{制作欧拉文件系统}
+本章节介绍如何构建适用于 aarch64 的 openEuler 文件系统镜像。
+
+\section{准备安装环境}
+\begin{enumerate}[(1)]
+    \item 下载 openEuler 的 rpi 的镜像文件
+\begin{minted}[bgcolor=lightgray!30,fontsize=\scriptsize]{bash}
+curl -O http://repo.openeuler.org/openEuler-24.03-LTS/raspi_img/\
+    openEuler-24.03-LTS-raspi-aarch64.img.xz
+xz -d openEuler-24.03-LTS-raspi-aarch64.img.xz
+\end{minted}
+    \item  准备 aarch64 的系统：
+\begin{minted}[bgcolor=lightgray!30,fontsize=\scriptsize]{bash}
+sudo losetup -P /dev/loop0 openEuler-24.03-LTS-raspi-aarch64.img
+sudo mount /dev/loop0p3 /media
+mkdir rpi
+sudo rsync -avzP /media/ rpi/
+sudo umount /media
+sudo losetup -d /dev/loop0
+sudo cp /usr/bin/qemu-aarch64-static rpi/usr/bin
+\end{minted}
+   \item 切换到安装环境
+\begin{minted}[bgcolor=lightgray!30,fontsize=\scriptsize]{bash}
+sudo mount --bind /dev rpi/dev
+sudo mount --bind /dev/pts rpi/dev/pts
+sudo mount -t proc proc rpi/proc
+sudo mount -t sysfs sys rpi/sys
+sudo chroot rpi /usr/bin/qemu-aarch64-static /bin/bash -i
+\end{minted}
+   \item 编辑 /etc/resolv.conf
+\begin{minted}[bgcolor=lightgray!30,fontsize=\scriptsize]{bash}
+nameserver 8.8.8.8
+nameserver 114.114.114.114
+\end{minted}

+dnf makecache
+dnf install git wget make gcc bison dtc m4 flex bc openssl-devel \
+    tar dosfstools rsync parted dnf-plugins-core tar
+\end{minted}
+    \item 创建工作目录
+\begin{minted}[bgcolor=lightgray!30,fontsize=\scriptsize]{bash}
+export WORKDIR=/root/build
+mkdir -p $WORKDIR
+cd $WORKDIR
+\end{minted}
+\end{enumerate}
+

+\subsection{安装 ukui 桌面系统 (可选)}
+ukui 是麒麟软件团队历经多年打造的一款Linux 桌面，主要基于 GTK 和 QT开发。与其他UI界面相比，ukui更加注重易用性和敏捷度，各元件相依性小，可以不依赖其他套件而独自运行，给用户带来亲切和高效的使用体验。
+
+\begin{enumerate}[(1)]
+    \item 安装 ukui
+\begin{minted}[bgcolor=lightgray!30,fontsize=\scriptsize]{bash}

+\begin{minted}[bgcolor=lightgray!30,fontsize=\scriptsize]{bash}
+Section "Device"
+    Identifier  "Rockchip Graphics"
+    Driver      "modesetting"
+
+### Use Rockchip RGA 2D HW accel
+#    Option      "AccelMethod"    "exa"
+
+### Use GPU HW accel
+    Option      "AccelMethod"    "glamor"
+    Option      "DRI"            "2"

+    Device      "Rockchip Graphics"
+    Monitor     "Default Monitor"
+EndSection
+
+### Valid values for rotation are "normal", "left", "right"
+Section "Monitor"
+    Identifier  "Default Monitor"
+    Option      "Rotate" "normal"
+EndSection
+\end{minted}
+    \item 切换用户界面（GUI）模式
+\begin{minted}[bgcolor=lightgray!30,fontsize=\scriptsize]{bash}
+systemctl set-default graphical.target
+\end{minted}
+   还原到文本模式，用下面命令：
+\begin{minted}[bgcolor=lightgray!30,fontsize=\scriptsize]{bash}
+systemctl set-default multi-user.target
+\end{minted}
+\end{enumerate}
+
+\subsection{设置第一次开机脚本，然后退出}
+\begin{minted}[bgcolor=lightgray!30,fontsize=\scriptsize]{bash}
+chkconfig --add first-run.sh
+chkconfig first-run.sh on
+dnf clean all
+exit
+\end{minted}
+

+umount -l $WORKDIR/rootfs/dev
+umount -l $WORKDIR/rootfs/proc
+umount -l $WORKDIR/rootfs/sys
+\end{minted}
+
+\section{制作镜像}
+\begin{enumerate}[(1)]
+\item 计算镜像容量
+\begin{minted}[bgcolor=lightgray!30,fontsize=\scriptsize]{bash}

+
+\item 格式化镜像
+\begin{minted}[bgcolor=lightgray!30,fontsize=\scriptsize]{bash}
+mkfs.ext4 -d $WORKDIR/rootfs rootfs.img
+\end{minted}
+\end{enumerate}
+rootfs.img 就是最后可以用 rockchip 的工具烧写到 MMC 上的欧拉系统。
+
+\section{退出并清理}
+\begin{minted}[bgcolor=lightgray!30,fontsize=\scriptsize]{bash}
+exit
+sudo umount -l rpi/dev/pts
+sudo umount -l rpi/dev
+sudo umount -l rpi/proc
