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)。
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)。
