      What were you trying to do that didn't work?

      When installing a system with /boot as a Software Raid, the system will not boot properly in case grub2-common created the wrapper but enter grub> prompt.

      Hopefully with Anaconda, the issue doesn't happen because Anaconda generates the wrapper by itself (which is, IMHO, a bug, it should let grub2-common handle this).
      This is however an issue when Leapp'ing a system from RHEL8 to RHEL9.

      The issue happens because the parameter --root-dev-only is passed to search command:

      search --no-floppy --root-dev-only --fs-uuid --set=dev ${BOOT_UUID}

      In case of Software Raid, this parameter breaks the functionality.

      Please provide the package NVR for which bug is seen:

      grub2-common-2.06-77.el9.noarch

      How reproducible:

      Always

      Steps to reproduce

      1. Install a RHEL8 system in UEFI with /boot on a SoftRaid
      2. Leapp it

      Expected results

      Boots on RHEL9 after upgrade

      Actual results

      Falls into grub> prompt
