系统配置
开始前先参照前面的内网完成相关组件的编译安装 https://wiki.waringid.me/x/XwC1B
System V
System V 是自 1983 年以来就在 Unix 和 Linux 等类 Unix 系统中被广泛应用的经典引导过程。它包含一个小程序 init，该程序设定 login (通过 getty) 等基本进程，并运行一个脚本。该脚本一般被命名为 rc，控制一组附加脚本的运行，这些附加脚本完成初始化系统需要的各项工作。
init 程序受到 /etc/inittab 文件的控制，被组织为用户可以选择的系统运行级别。在 LFS 中，运行级别定义为：
- 0 — 停止运行
- 1 — 单用户模式
- 2 — 用户自定义模式
- 3 — 完整的多用户模式
- 4 — 用户自定义模式
- 5 — 拥有显示管理器的完整多用户模式
- 6 — 重启系统
通常的默认运行级别是 3 或 5。
优点
- 完备的，已经被详细理解的系统。
- 容易定制。
缺点
- 引导速度较慢。一个中等速度的基本 LFS 系统从第一个内核消息开始，到出现登录提示符为止，需要 8-12 秒的引导时间，之后还需要约 2 秒启动网络连接。
- 串行执行引导任务。这与前一项缺点相关。引导过程中的延迟 (如文件系统检查) 会拖延整个引导过程。
- 不支持控制组 (cgroups) 和每用户公平共享调度等高级特性。
- 添加脚本时，需要手动决定它在引导过程中的次序。

管理设备
创建自定义 Udev 规则
bash /usr/lib/udev/init-net-rules.sh
cat /etc/udev/rules.d/70-persistent-net.rules
sed -e '/^AlternativeNamesPolicy/s/=.*$/=/' \
/usr/lib/udev/network/99-default.link \
> /etc/udev/network/99-default.link
udevadm test /sys/block/hdd
sed -e 's/"write_cd_rules"/"write_cd_rules mode"/' \
-i /etc/udev/rules.d/83-cdrom-symlinks.rules
