Unmount fauls after I test an overlayfs with a casefold subdir:
Testing an overlayfs on a casefold fs with non-casefolded dirs
Test using casefolded dir - should fail
overlayfs: failed to resolve '/mnt/casefold': -2
mount: /mnt/merged: special device overlay does not exist.
dmesg(1) may have more information after failed mount system call.
Test using a dir with a casefold subdir - should mount
overlayfs: upperdir is in-use as upperdir/workdir of another mount, accessing files from both mounts will result in undefined behavior.
overlayfs: workdir is in-use as upperdir/workdir of another mount, accessing files from both mounts will result in undefined behavior.
ls: cannot access '/mnt/merged/dir/casefold': No such file or directory
umount: /mnt: target is busy.
