[Bug 396949] Re: mounted cdrom doesn't display long filenames

[Robert J. Schulz]

I have kind of this in

Linux sandra-nb 2.6.31-15-generic #50-Ubuntu SMP Tue Nov 10 14:53:52 UTC

But these 3 Lines will only be logged if i mount it without joliet:

sudo mount -t iso9660 -o ro /dev/cdrom /media/cdrom

Finally i found a "workaround" in using option nojoliet for the mount
command:

rosa at sandra-nb:/usr/src$ sudo mount -t iso9660 -o ro,nojoliet /dev/cdrom /media/cdrom
rosa at sandra-nb:/usr/src$ ls /media/cdrom
riess_~1.mpg

And i found further discussions on whether  "Interleaved files" will
sometimes become supported by the kernel...
