1.11.2 Password for the System
Administrator root
If you have not chosen Use this Password for the System Administrator in the previous
step, you will be prompted to enter a Password for the System Administrator root.
Otherwise this conguration step is skipped.
root is the name of the superuser, or the administrator of the system. Unlike regular
users (who may or may not have permission to access certain areas or execute certain
commands on the system), root has unlimited access to change the system congura-
tion, install programs, and set up new hardware. If users forget their passwords or have
other problems with the system, root can help. The root account should only be
used for system administration, maintenance, and repair. Logging in as root for daily
work is rather risky: a single mistake could lead to irretrievable loss of system les.
For verication purposes, the password for root must be entered twice. Do not forget
the root password. Once entered, this password cannot be retrieved.
The root can be changed any time later in the installed system. To do so run YaST
and start Security and Users > User and Group Management.
WARNING: The root User
The root user has all the permissions needed to make changes to the system.
To carry out such tasks, the root password is required. You cannot carry out
any administrative tasks without this password.
