最近光猫玩得起劲，发现busybox真的是好东西
这研究不要紧，被我发现了buxybox自带init命令！
本来想要自己做一个BusyOS的，结果发现已经有成熟的方案了:alpine!
手中没有x86的主机，所以我把目光放到了我的闲置Cm311-1 (S905L3)
(上次玩的是MGV3000，这两台机器主板相似度达到了惊人的90%)
折腾思路
alpine官网很快，即使安装完alpine apk也不需要换源
- standard 是网络安装镜像
- EXTENDED 是本地安装镜像
- NETBOOT 需要远程服务器，是网络启动镜像
- RASPBERRY PI版本和GENERIC ARM版本与我们的启动方式(android U-BOOT)不兼容
- MINI ROOT FILESYSTEM 只支持docker和WSL等虚拟化容器
- VIRTUAL 适用于虚拟机
- XEN 与arm不兼容
这就很头疼了，因此我们需要以armbian为跳板，用MINI ROOT FILESYSTEM安装基础外围
使用u盘启动
额......请看我的文章，我就不赘述了
安装alpine
我们需要让armbian-install帮助我们调整分区
第一次U盘启动可能需要设置，按照我的教程走就行

armbian:~:#
在出现 Copying ROOTFS 时Ctrl+C终止
右键复制链接，使用curl下载并解压到ddbr
cd /ddbr/install
rm -rf *
curl -L https://dl-cdn.alpinelinux.org/alpine/v3.19/releases/aarch64/alpine-minirootfs-3.19.1-aarch64.tar.gz | tar xz
安装设置必须软件包
首先切换到alpine，安装必须外围
chroot . sh
# OpenRC 系统管理框架
apk add openrc
# 可选，用nano代替vi
apk add nano
# 使用ssh
apk add openssh
nano /etc/ssh/sshd_config
rc-status enable sshd default
修改两处：17、36行
然后运行passwd，更改ROOT密码（否则SSH一定无法登录）
继续复制命令并运行：
# 安装网络管理
apk add networkmanager
rc-update add networkmanager default
# 安装系统工具
apk add chrony util-linux tzdata
cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
echo "Asia/Shanghai" > /etc/timezone
rc-status chronyd default
rc-update add devfs boot
rc-update add procfs boot
rc-update add sysfs boot
rc-update add devfs boot
rc-update add procfs boot
rc-update add sysfs boot
rc-update add networking default
rc-update add sshd default
rc-update add chronyd default
# 重启
sync
exit
reboot
拔掉u盘启动系统，然后找服务器IP就可以SSH登录了！

将/lib/modules从U盘拷过去即可，很简单
