FreeBSD freebie 5.3-BETA1 FreeBSD 5.3-BETA1 #0: Sat Aug 21 08:19:34 UTC 2004     root at  i386

On a Solaris UNIX system (Solaris 8 or 9 will do):

> sudo /usr/sbin/mount freebie:/cdrom /mnt
> ls -l /mnt

Not only are the date stamps wrong, but also the file sizes and the types of the files.  Notice that the directory "Solaris_9" is coming up as a file.
Mount a CD-ROM using mount_cd9660 on the FreeBSD machine.

Have it shared (read only or read write).

Try to NFS mount the shared file system onto a Solaris machine.

I suspect that the CD ROM may need to include Joliet extensions.
The CD ROM I have used in this example is Solaris 9 12/03 1 of 2.

I believe that almost any CD ROM from a commercial vendor will exhibit this problem.
The workaround is to mount using NFS version 2.
