With this fairly standard and simple ext4 setup (see
https://openqa.opensuse.org/tests/1443345#step/partitioning_filesystem/9 for
the YaST view), the installation fails with grub2-install complaining: "failed
to get canonical path of `/boot/grub2/i386-pc'."

This failure also happens in lvm-encrypt-separate-boot and autoyast_multi_btrfs
tests, but doesn't appear to affect standard cryptlvm or btrfs setups.

My guess
