>Description:

I created a test UDF image, which can not be mounted with mount_udf - it fails
with mount_udf: Cannot mount /dev/vnd0d on /mnt: Invalid argument.

The image was created with crappy software (names hidden to protect the
guilty), but it can be used just fine on Windows 7 for example.

udfclient fails as well (sees no files in it).

>How-To-Repeat:
Download http://www.netbsd.org/~martin/test.iso and try to mount it.

>Fix:
yes please (and while there, add -t udf support to makefs, which would save
me from using that crappy unnamed software...)
