May this image contain a UDF file system (instead of ISO9660)?

In that case you need to vnconfig it with a geometry specification,
so the vnd gets 2048 byte blocks, and then use mount_udf instead of
mount_cd9660 (I typically use /dev/vnd0d for that, unless something very
special is going on or it is a Sun image with explicit disklabel).
