Fixed In Version: Doc Type: Known Issue
Doc Text:
Cause: Some rhel-8.4 images does not have the parameter "GRUB_DEFAULT=saved" in the /etc/default/grub file. Consequence: When the leapp OS upgrade reboots, the "new" reboot is still at rhel-8.4 instead of rhel-9.2 Workaround (if any): Adding the parameter "GRUB_DEFAULT=saved" in /etc/default/grub before doing the OS upgrade Result: The leapp OS upgrade reboot will boot on the rhel-9.2 system.

Description Alex Stupnikov 2024-02-26 11:11:11 UTC 
Description of problem:
Because of some bug or build system problems RHEL 8.4 images were built without "GRUB_DEFAULT=saved" definition in /etc/default/grub. As a result, Leapp fails to update grub menu properly and after reboot director boots RHEL 8 again instead of RHEL 9.

More details are provided in https://access.redhat.com/solutions/7057531. This problem affects all RHOSP 16.2 director nodes bootstrapped from standard RHEL 8.4 images. I want to ask you to consider adding this information to list of known issues affecting FFU from RHOSP 16.2 to RHEL 17.1.
