Hmm. AFAICR the nbd in the kernel is still the old version (read: dead
code). You need to get enbd from http://www.it.uc3m.es/~ptb/nbd/
read and compile as normal. You need to have the kernel nbd compiled as
a module. ENBD then replaces that module but uses the same kernel hooks.
There's been a thread on the enbd mailing list about removeable stuff
and this seems to be being developed rapidly. I would therefore suggest
you get the CVS copy and use that.
ENBD relies on the kernel's ability to handle large files. In theory, so
long as you're using a 2.4.x kernel you should be able to export the
full DVD. In theory. If you get it to work then it would probably be
worthwhile to subscribe to the list and let people know. The author
still isn't convinced that 2GB+ support is fully working in the 2.4.x
kernels so the results of any testing you can do would be gratefully
received.
