将模块从内核中独立出来,不必预先『绑』在 kernel codes 中。这样做有三种优点: 第一, 将来修改 kernel 时,不必全部重新compile,可节省不少时间;第二, 若需要安装新的 modules ,不必重新 compile kernel,只要插入 (通过insmode指令) 对应的 modules 即可;第三,减少内核对系统资源的占用,内核可以集中精力做最基本...
《Linux kernel in a nutshell》 Kernel Parameters ~~~ The following is a consolidated list of the kernel parameters as implemented (mostly) by the __setup() macro and sorted into English Dictionary order (defined as ignoring all punctuation and sorting digits before letters in a case insensitive...

The special file /dev/initrd is a read-only block device, this device is a RAM disk that is initialized (e.g., loaded) by the boot loader before the kernel is started. After loading the additional modules, a new root filesystem (i.e., the normal root filesystem) is mounted from a...

except that some necessary components may be loadable kernel modules rather than part of the main kernel. On some machines, you may need to load these kernel modules before the true root filesystem is mounted. We’ll cover this problem and its initial RAM filesystem workaround solutions in 6....
A.conffile usually accounts for a single module, in which case the convention is to use the name of that module as the filename. On the other hand, groups of modules can be loaded with a single configuration file as well. Regardless,a.conffile is just a list of kernel module names, ...
lsmod: provides a list of the kernel modules currently loaded on Linux O/S. modprobe: a command used to add or remove kernel modules on Linux O/S. modinfo: a command that shows information about the kernel module on Linux O/S.
