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
