Because there is no mount, there is only a separate partition.

5. Switch to the original system for execution: chroot / sysroot/

The original system is under sysroot, how to change the password of the original system?

1. Switch to the original system environment. With command; chroot / sysroot/

6. Change the root password: passwd root

Small square that appears: defined as English: LANG=en

Execute: passwd root command, you can change the password.

For example, change to: password1234

7. Execute: touch / .autorelabel

After the change is completed, one more key operation, touch / .autorelabel, will be done.

Then restart the virtual machine.

Try logging in with your new password.

Or:

Finally, enter the command [touch / .autorelabel]

Create a .autorelabel file in the / directory, and if this file exists, the entire file system will be relabeling when the system restarts.

And the command [exit] to exit

And command [reboot] to restart.

The following system can log in.
