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

I want to display the GRUB menu but I can't update the GRUB configuration.

What is the impact of this issue to you?

I can't select boot entries to rescue my system.

Please provide the package NVR for which the bug is seen:

grub2-common-2.06-92.el9.noarch

How reproducible is this bug?:

100%

Steps to reproduce

1. Create a centos-stream9 image with bootc-image-builder, ref. https://github.com/osbuild/bootc-image-builder
2. Create grub config

   # cat /etc/default/grub 
   GRUB_TIMEOUT=5
   

3.  Update the config

   # grub2-mkconfig -o /boot/grub2/grub.cfg

Expected results

The menu is updated. The menu is shown after next boot.

Actual results

/usr/sbin/grub2-probe: error: failed to get canonical path of `composefs'.

Additional notes

I also tried to update during container build but that one failed, too:

STEP 7/8: RUN grub2-mkconfig -o /boot/grub2/grub.cfg
/usr/sbin/grub2-probe: error: failed to get canonical path of `overlay'.
Error: building at STEP "RUN grub2-mkconfig -o /boot/grub2/grub.cfg": while running runtime: exit status 1
