How do I enter emergency mode? In CentOS/RHEL

 

 

 

In case of a malfunctioning system, systemd emergency targets can be used. In the emergency target, it does not try to mount the root filesystem. In case the root system file is not working, this should be the correct target. This should be the emergency target which still requires a password. In the case of forgetting your root user account password.
