Utility os-prober uses grub-probe (and grub-mount) in 50mounted-tests
on line 48 [3]:
mounted=
if type grub-mount >/dev/null 2>&1 && \
   type grub-probe >/dev/null 2>&1 && \
   grub-mount "$partition" "$tmpmnt" 2>/dev/null; then
        mounted=1
        type="$(grub-probe -d "$partition" -t fs)" || true
        if [ "$type" ]; then
                debug "mounted using GRUB $type filesystem driver"
        else
                debug "mounted using GRUB, but unknown filesystem?"
                type=fuseblk
        fi
else

When running os-prober it outputs the following in the syslog:

As you can see, it thinks /dev/sda6 a 'bfs' partition, causing script
83haiku to fail.
