Problem with vnconfig and ISO images

[Marc Wiz]

I'm using FreeBSD 4.9

I used to be able to mount an ISO image (disk file) using vnconfig
on 4.7 and 4.8.  Now I cannot.


-su-2.05b# vnconfig  -c vn2c /stage/daily-1.iso
-su-2.05b# file /stage/daily-1.iso
/stage/daily-1.iso: ISO 9660 CD-ROM filesystem data
-su-2.05b# mount -t cd9660 /dev/vn2c /mnt
cd9660: /dev/vn2c: Invalid argument


In my kernel config I have:

pseudo-device   vn      4       # 4 vnodes for vnconfig

Has anyone else run into any problems like this?

Thanks,
Marc
