Hello, I have SUSE_BTRFS_SNAPSHOT_BOOTING set to true in /etc/default/grub but there is no entry for booting from a snapshot in my GRUB menu, only the two entries for Tumbleweed, one is for directly booting the system, the other is the advanced boot selection with the last two kernel versions and their recovery versions. I am using /boot/grub2/custom.cfg with a few manual entries and I have also set GRUB_DISABLE_OS_PROBER to true. The rest should be default settings. Is there a way to troubleshoot this?
