一键生成可定制的Debian rootfs，支持riscv64

whycan晕哥 LV 9

论坛之前已经有一个使用debootstrap生成Debian rootfs的教程了，但我一直使用的是一个Github上的自动生成脚本来生成，优势主要是：

更方便，跑一个脚本生成直接可用的rootfs，无需更多设置

包括版本和预装包都完全可定制

生成的rootfs可以直接chroot进去，所需的依赖自动安装

最近给D1s定制rootfs，为了支持riscv64，我对原作者的脚本进行了一定的魔改，在此分享一下使用方法：

首先clone仓库到本地：

git clone https://github.com/SdtElectronics/debian-rootfs.git

然后安装相关依赖

apt-get install multistrap binfmt-support qemu-user-static

最后运行一条命令即可生成：

./make-rootfs.sh ARCHITECTURE
支持的ARCHITECTURE有：

amd64
arm64
armel
armhf
i386
mips
mipsel
powerpc
powerpcspe
ppc64el
s390x
riscv64

注意要是想生成riscv64的rootfs，需要改用如下命令（因为risc-v目前还在Debian port源下）：

sudo ./make-rootfs.sh riscv64 multistrap_debian-ports.conf

生成的rootfs在build/目录下。
若脚本运行时出现类似错误信息：

The following signatures couldn't be verified because the public key is not available

需要手动给 /usr/sbin/multistrap 的文件打上这个补丁。

更多信息，可以参考原仓库：
https://github.com/SdtElectronics/debian-rootfs

一些进阶用法：
更改预装包：
修改multistrap.conf中的packages字段即可。注意要生成riscv64的rootfs，需要修改的是multistrap_debian-ports.conf。
更改版本：
修改multistrap.conf中的suite字段即可。合法的值可以是版本名，或者是stable, testing和sid。注意要生成riscv64的rootfs，需要修改的是multistrap_debian-ports.conf。
异构chroot：
异构chroot所需的qemu等依赖，脚本都已经自动装好，直接chroot ./ 即可。

嗯，感谢楼主分享，我的哪吒就是这么做debian rootfs 的。

么做debian roo

请问有人用了这个工具了吗？做出来无法启动呢，出现错误信息如下：
