Linux reinstall 是一款功能强大的服务器系统一键重装脚本，基于萌咖的一键重装脚本近期经过更新，已经支持 Debian 11/Ubuntu 20.04 等新系统，加入了对 Oracle ARM 机型的支持，现对该脚本进行了一些优化，以增强重装脚本的适用性和实用性。

一、Linux reinstall 脚本介绍
脚本特色：
- 全自动无人值守安装；
- 支持各主流VPS商家；
- 重装前可预先指定 ssh 密码、端口、固件、镜像源等参数，执行重装命令时，如果未指定密码、端口。重装后的系统默认用户：root，默认端口：22，默认密码：LeitboGi0ro，首次 ssh 机器后请立即修改密码；
- preseed 过程针对 Debian 做了大量优化，预置常用组件，永久更改 DNS 为 CloudFlare、Google（需进系统后手动安装 resolvconf：echo “N” | apt install resolvconf -y ），vim 支持鼠标终端复制，不同文件类型不同彩色显示，ssh 连接欢迎页面显示系统占用、IP 信息，软件数更新提示；
- 双栈（同时拥有 ipv6 和 ipv4 地址）机型默认优先配置 ipv4 网络，开机后请手动配置 ipv6 网络，针对纯 ipv6 机型的支持正在开发中；
- 对于 Debian 系统，安装时附带的固件源为国外，国内 VPS 连接速度很慢，长时间连接无速度往往会下载失败，可指定 –cdimage ‘cn’，将源切换到国内中科大的，以提高下载速度；
- 安装时避免进入低内存模式（Debian 特有）后需要进行手动配置，导致无法自动化部署安装的内存量检测阈值，256M 以上机型即使安装时进入低内存模式，也可以自动化进行，这点对内存少于 1GB 的机型尤为重要。已在搬瓦工 512M 机型做过测试，萌咖原版脚本重装 Debian 11 时，会跳出低内存模式手动配置，自动化安装过程无法继续，首先必须手动选择需要加载的硬件驱动，项目多且复杂，不同机器的硬件各有差别，选择稍有错误，就会导致驱动安装不全，最后系统安装失败，本脚本可保证小内存 VPS 低内存模式自动化安装过程顺利进行，低于 768M 小内存机型安装前执行脚本时，不要附带“-firmware”或“-firmware –cdimage”参数，否则重启后无法进入低内存模式安装界面，导致安装失败。
- 由于 Ubuntu 22.04 官方移除了对“initrd.img”和“vmlinuz”两个网络引导安装文件的支持，导致目前并无很方便重装 Ubuntu 22.04 的方法，Ubuntu 母公司 Canonical 强推的 Cloudinit 自动部署方式对机器要求极高，必须有虚拟化支持，这是很多已经在母机上被虚拟化后的 VPS 所不具备的。目前仅甲骨文机器 CPU 仍支持虚拟化，所以市面上所有号称能重装成 Ubuntu 22.04 的一键脚本都是假的，无法完成安装，切勿相信。鉴于 Canonical 经常喜欢做焚烧自家亲妈的行为，未来不会对后续 Ubuntu 系统重装做任何支持。
- CentOS 8 已被官方放弃，9 以后的 stream 版，成为一项供 Redhat Linux 测试 bug 的上游服务，不再具备 7 及以前版本可完备替代 Redhat Linux 的稳定成熟特性，后续也不再对 CentOS 进行支持。
