   rpmextract会把rpm中的内容解压到当前目录，解压出来的目录结构以根目录(/)为基准

3. 解压下载下来的android rpm文件

   cd /
   sudo rpmextract.sh ~lujun9972/android/android-x86-7.1-r2.i686.rpm
   

4. 往 /etc/grub.d/40_custom 中添加如下内容

   menuentry "Android 7.1-r2" {
   search --set=root --file /android-7.1-r2/kernel
   linux /android-7.1-r2/kernel quiet root=/dev/ram0 androidboot.selinux=permissive
   initrd /android-7.1-r2/initrd.img
   }
   

   可以通过执行下面脚本来添加

   cat >>/etc/grub.d/40_custom <<'EOF'
   menuentry "Android 7.1-r2" {
   search --set=root --file /android-7.1-r2/kernel
   linux /android-7.1-r2/kernel quiet root=/dev/ram0 androidboot.selinux=permissive
   initrd /android-7.1-r2/initrd.img
   }
   EOF
   

5. 运行 grub-mkconfig 更新grub配置文件

   sudo grub-mkconfig -o /boot/grub/grub.cfg
   

6. 重启之后就能看到"Android 7.1-r2"的启动菜单了
