This allows the kernel to be dynamic at startup (load modules based on the devices that are found) but not dynamic throughout operation.

这允许内核在启动时是动态的(根据找到的设备加载模块)，但并不是在整个操作过程中都是动态的。

One of the most straightforward ways is to create dual-boot setups, where multiple OSes are installed on a single machine, with a choice being made at startup as to which one to load.

最简单的方法就是创建一个双启动设置，即将多个操作系统装在同一台计算机上，在启动时可以选择所加载的系统。
