系统启动中initrd.img起什么作用？

[冲浪板]

有模块不假，但是，仅有模块可跑不起来，因为她里边还有初始化文件等等...等等...
不相信你就把她解开，然后file看看。

没听说过软盘上的linux?minilinux?文件系统就是这个，当然为了小型话还要改造一下下。

当然要有初始化文件了，出门打酱油肯定要穿鞋啊。也可以不穿，全编译成内核啊。usb的linux系统是需要它的。
我说的不详细罢了，ＬＺ要是真想深入就google了啊。文件系统怎么是软盘上的linux。ＬＯＯＫ：

Ｄefinition１：
A directory structure contained within a disk drive or disk area. The total available disk space can be composed of one or more filesystems. A filesystem must be mounted before it can be accessed. To mount a filesystem, you must specify a directory to act as the mount point. Once mounted, any access to the mount point directory or its subdirectories will access the separate filesystem.

Ｄefinition２：
A method of organising files on a disk, eg NTFS, FAT,EXT,XFS,REISERFS.

Ｄefinition３：
A data structure or a collection of files. In Unix, filesystem can refer to two very distinct things, the directory tree or the arrangement of files on disk partitions.

Ｄefinition４：
the structure of files on a disk medium which is visible via the operating system, ie the structure of files which a Unix user can see using "ls" and other tools.

Ｄefinition５：
A software mechanism that defines the way that files are named, stored, organized, and accessed on logical volumes of partitioned memory.

Ｄefinition６：
In computing, a file system is a method for storing and organizing computer files and the data they contain to make it easy to find and access them. File systems may use a storage device such as a hard disk or CD-ROM and involve maintaining the physical location of the files, or they may be virtual and exist only as an access method for virtual data or for data over a network (e.g. NFS).

真郁闷，network还是不能自动配置，每次手动配置尽管不算麻烦，但让人感觉很不爽

另：如果我想在机子启动时就以root身份自动运行一个命令“XXX”，该怎么做？
还有：机子启动时configuring network interfaces总是failed，需要启动后手动sudo /etc/init.d/networking restart才能正常使用网络，是怎么回事？

可以修改/etc/rc.local
写在里面的命令会在启动gdm前，以root权限执行
我的cpufreq也有这样的问题，一定要自己rmmod，再重新modprobe后才能正常调节-__-
