	Linux From Scratch 12.2/chapter07_kernfs — Spanish	/dev/*
	Linux From Scratch 12.2/chapter07_kernfs — Chinese (Simplified Han script)	Applications running in userspace utilize various file systems created by the kernel to communicate with the kernel itself. These file systems are virtual: no disk space is used for them. The content of these file systems resides in memory. These file systems must be mounted in the $LFS directory tree so the applications can find them in the chroot environment.	内核对外提供了一些文件系统，以便自己和用户空间进行通信。它们是虚拟文件系统，并不占用磁盘空间，其内容保留在内存中。

	Linux From Scratch 12.2/chapter07_kernfs — Spanish	Mounting and Populating /dev
	Linux From Scratch 12.2/chapter07_kernfs — Chinese (Simplified Han script)	During a normal boot of an LFS system, the kernel automatically mounts the <systemitem class="filesystem">devtmpfs</systemitem> file system on the <filename class="directory">/dev</filename> directory; the kernel creates device nodes on that virtual file system during the boot process, or when a device is first detected or accessed. The udev daemon may change the ownership or permissions of the device nodes created by the kernel, and create new device nodes or symlinks, to ease the work of distro maintainers and system administrators. (See <xref linkend='ch-config-udev-device-node-creation'/> for details.) If the host kernel supports &devtmpfs;, we can simply mount a &devtmpfs; at <filename class='directory'>$LFS/dev</filename> and rely on the kernel to populate it.	用设备文件填充 <filename class="directory">/dev</filename> 目录的推荐方法是挂载一个虚拟文件系统 (例如 <systemitem class="filesystem">tmpfs</systemitem>) 到 <filename class="directory">/dev</filename>，然后在设备被发现或访问时动态地创建设备文件。这个工作通常由 Udev 在系统引导时完成。然而，我们的新系统还没有 Udev，也没有被引导过，因此必须手工挂载和填充 <filename class="directory">/dev</filename>。这可以通过绑定挂载宿主系统的 <filename class="directory">/dev</filename> 目录就实现。绑定挂载是一种特殊挂载类型，它允许在另外的位置创建某个目录或挂载点的映像。运行以下命令进行绑定挂载：

	Linux From Scratch 12.2/chapter07_kernfs — Chinese (Simplified Han script)	But some host kernels lack &devtmpfs; support; these host distros use different methods to create the content of <filename class="directory">/dev</filename>. So the only host-agnostic way to populate the <filename class="directory">$LFS/dev</filename> directory is by bind mounting the host system's <filename class="directory">/dev</filename> directory. A bind mount is a special type of mount that makes a directory subtree or a file visible at some other location.
