3. Press Ctrl+X to enter low-level editing mode.

4. Run the following commands to set a new password. In this example, westos is the new password:

   # Enter shell mode
   chroot /sysroot/
   # Set the new password
   echo westos | passwd --stdin root
   # Create a new SELinux security context
   touch /.autorelabel
   # Exit shell mode
   exit
   # Exit edit mode
   exit
