This root device is actually a virtualized device coming from the hypervisor, but your servers won't know that.
根设备实际上是来自系统管理程序的一个虚拟的设备，但您的服务器不会知道这一点。
The kernel checks the hardware and mounts the root device and then looks for the init program on the root filesystem and executes it.
内核检查硬件并加载根设备，然后查找根文件系统的init程序并执行该程序。
At this stage, the second-stage boot loader checks the system hardware, enumerates the attached hardware devices, mounts the root device, and then loads the necessary kernel modules.
在这个阶段中，第二阶段的引导加载程序会检测系统硬件、枚举系统链接的硬件设备、挂载根设备，然后加载必要的内核模块。
We then loop, rescanning the SCSI bus (by echoing a command to a special file in the /proc pseudo-filesystem and calling devfsd) until the root device (/dev/sda1 in my case) is present.
然后我们进行循环，重新扫描SCSI总线（通过将命令回送到 /procpseudo-filesystem中的特殊文件，并调用devfsd ），直到出现根设备（我的例子中为 /dev/sda1）。
There is a timing window within the kernel, which means that often, the kernel will proceed to try to mount the root device before it has had a chance to be properly detected or initialized.
内核中有定时窗口，这意味着内核经常在其能够被正确的监测和初始化之前尝试安装根设备。
Set up parameter area and construct parameter structures and tags (this is an important step, as boot parameters are used by the kernel in identifying root device, page size, memory size and more).
设置参数区域并构造参数结构和标记(这是重要的一步，因为内核在标识根设备、页面大小、内存大小以及更多内容时要使用引导参数)。
Because label, UUID, and friendly name will bond with a dedicated device forever, no matter what device ID it has or what device name it gets, your system will always find your root file system disk.
由于标签、UUID和友好的名称将永远与专用设备绑定在一起，因此不管拥有什么设备ID或者使用什么设备名称，系统总是能够找到根文件系统磁盘。
If you use the device mapper multi-path (DMMP) tool for your multi-path storage, then you can use a friendly name for your root file system to avoid the device being renumbered by DMMP after reboot.
如果将设备映射程序多路径(DMMP)工具用于多路径存储，则可以将友好的名称用于根文件系统以避免设备在重新启动后被dmmp重新编号。
Use the label, UUID, or friendly name instead of the device name for the root file system mount.
对根文件系统挂载使用标签、UUID或友好的名称而非设备名称。
The reason for the additional LUN is that the root file system is in use at this time and DMMP cannot add it to the device map; therefore, you cannot get that name for the root partition.
添加lun的原因是，使用的根文件系统和DMMP无法将它添加到设备映射；因此，无法对根分区应用该名称。
When you're using RAID for the root partition, there is more than one device involved.
当你在根分区使用RAID，包括了一个以上的设备。
Change PCI Device Boot Priority to the adapter your root file system disk is using (as in Figure 2 below), if your Linux is installed on a local Planar SAS disk.
如果您的Linux安装在本地PlanarSAS磁盘中，请将PCIDeviceBootPriority更改为根文件系统磁盘正在使用的适配器(如下面的图2所示)。
It would supply an argument of foo0 to devfs_register , thus telling the kernel that a new foo0 device should be created at the root of the devfs namespace.
它会提供一个foo0的参数给devfs_register，从而告诉内核应该在devfs名称空间的根目录创建一个新的foo0设备。
The cannot mount rootfs error always happens when your system tries to switch the initrd root file system to the real root file system disk with the device name in this configuration.
当系统尝试将initrd根文件系统切换到拥有此配置中的设备名称的实际根文件系统磁盘时，经常会出现can notmount rootfs错误。
In response, devfs_register adds the foo0 device node to the root of the devfs namespace, and records that this new foo0 node should map to the foo device driver in the kernel.
相应的，devfs_register在devfs名称空间的根目录添加foo0设备节点，并记录这个新的foo0节点应该映射到内核中的foo设备驱动程序。
Only root can mount or unmount the device but users can execute binaries and use the "sticky bit" (covered later).
只有root可以装载或者缷载设备，但是用户可以执行二进制文件和使用“stickybit”(稍后介绍)。
Using the following command to check the ID for your root file system device with the device UUID you get from step 1.
使用以下命令检查带有从第1步中得到的设备UUID的根文件系统设备的ID。
You can now see in your device that Superuser app is prompting you to allow the ADB root access.
现在，您可以看到您的设备，超级用户的应用程序是提示你，让亚行的根访问。
The root directory entry (dentry) object is cached here also, as is the block device on which this file system resides.
根目录条目(dentry)对象也缓存在这里，因为它是文件系统所在的块设备。
How does one designate the root of a handheld device?
如何指定一个手持设备的根？
A Device can be accessed directly from the Host with its PortIdentifier, or can be found by traversing the USB Bus starting from the root hub.
可以用一台Device的PortIdentifier直接从Host访问它，也可以通过从roothub开始遍历usbBus找到它。
While this does not protect data from a root compromise that can monitor the user inputting the password, it can provide protection for a lost device without file system encryption.
这并不会保护数据以防可以监听用户输入密码的根权限入侵，它可以为丢失的没有文件系统加密的设备提供保护。
For example, it can be used for root canal disinfection, which can not be realized by the traditional plasma device.
例如，等离子体喷流装置能够应用于牙齿根管的杀菌消毒，而这恰恰是传统的等离子体装置所不能实现的。
