Description

Reassigning to dracut for review, this is a post-installation task. dracut uses sulogin to enter the emergency shell since https://github.com/dracutdevs/dracut/commit/32f68c1f9ac3720e8ce4b95a09c0ce680d5da786 , so this hack no longer works. As an alternative, boot from a live CD/USB and mount the root partition from there. Ravindra, it seems that the product documentation you referenced for RHEL 9.0 Beta ( https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9-beta/html/configuring_basic_system_settings/changing-and-resetting-the-root-password-from-the-command-line_configuring-basic-system-settings ) on Chapter 23.3. "Resetting the root password on boot” is based on RHEL 8 and no longer aplicable for RHEL 9 beta. Entering into a chroot environment in order to reset the root password for RHEL 9 beta can now be done under the rescue boot parameters. In addition, the current documentation for RHEL 9 beta -Chapter 23.3 - Procedure #4 : The procedure states that "The switch_root prompt appears". This is also no longer applicable. After entering rescue mode and pressing the Enter key for maintenance, the sh-5.1# prompt now appears immediately. After this step, all following steps on current documentation can now be done successfully. New Steps: 1. Reboot the system and, on the GRUB 2 boot screen, use the down arrow key on your keyboard to select rescue mode. Press the e key to interrupt the boot process. Red Hat Enterprise Linux (0-rescure-XXXXXXXXXXXXXXXXXXXXXXXXXX) 9.0 2. Go to the end of the line that starts with linux. 3. Add rd.break to the end of the line that starts with linux. 4. Press Ctrl+x to start the system with the changed parameters. 5. Press the Enter key to enter maintenance mode. The sh-5.1# prompt appears. 6. Remount the file system as writable: mount -o remount,rw /sysroot 7. Enter the chroot environment: chroot /sysroot 8. Reset the root password: passwd 9. Enable the SELinux relabeling process on the next system boot: touch /.autorelabel 10. Exit the chroot environment: exit 11. Exit maintenance mode: exit —----------------------------------------- I hope this is beneficial. Thank you @David Silver!!!! The documentation for rhel 9 is still incorrect and needs to be updated. The documentation at step 23.3 step 1 needs to specify that the rescue kernel option needs to be selected with grub2. https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html/configuring_basic_system_settings/changing-and-resetting-the-root-password-from-the-command-line_configuring-basic-system-settings *** Bug 2092132 has been marked as a duplicate of this bug. *** *** Bug 2092150 has been marked as a duplicate of this bug. *** Let's revert this behaviour to rhel8 one. (no password) *** Bug 2056192 has been marked as a duplicate of this bug. *** I have a quicker way to reset root password in RHEL9. 0. ctrl + e 1. In linux line change ro to rw and add init=/bin/bash at the end of the line. 2. ctrl +x 3. passwd 4. touch ./autorelabel 5. exec /sbin/init (In reply to Łukasz Filipek from comment #15) > I have a quicker way to reset root password in RHEL9. > > 0. ctrl + e > 1.

In linux line change ro to rw and add init=/bin/bash at the end of the line. 2. ctrl +x ===> mount -o remount,rw / ==> As without it, it is throwing an "authentication token manipulation error" 3. passwd 4. touch ./autorelabel 5. exec /sbin/init Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
