In Linux, regular users and superusers are allowed to access services via password authentication. In the case a regular user can’t remember their password, a superuser can reset the password of a regular user right from the terminal. However, what if the root user loses their password? T...
meaning that when you execute the program, it runs as though the file owner is the user instead of you. Many programs use this setuid bit to run as root in order to get the privileges they need to change system files. One example is the passwd...
Grant Root Privileges To New User Let’s say you need to create a new user and grant him root access to the server. To create a user with exactly the same privileges as root user, we have to assign him the same user ID as the root user has (UID 0) and the same group ID (GID ...
With great power comes great responsibility. Root user gives you complete power over the system and hence it should be used with great caution. Root user can access system files and run commands to make changes to the system configuration. And hence, an incorrect command may destroy the system...
The point where the kernel starts its first user-space process, init, is significant—not just because that’s where the memory and CPU are finally ready for normal system operation, but because that’s where you can see how the rest of the system builds up as a whole. Prior to this ...

The root user account is the primary administrator account on a Linux system. It has unrestricted access to the file system. It allows you to configure, change, or delete any settings. This tutorial explained how to change or reset the forgotten root user password....

Root filesystem mount User space start CPU检查 内存检查 设备总线发现 设备发现 辅助内核子系统设置(网络等) 挂载根文件系统 用户空间启动 The first steps aren’t too remarkable, but when the kernel gets to devices, a question of dependencies arises. For example, the disk device drivers may depend...
