Multi-volume CDs are a set of CDs, all with the same filetree, but with
the actual files distributed between the CDs. That means, you can traverse
the tree independently of what CD is in the drive, but have to insert the
correct one, if you actually want to read some file.

This means, that support of multi-volume CDs requires some user interaction
from the filesystem, which is quite a novel concept.

I don't know about any particular bugs in the code. It could well be, that
the CD in question violates the spec (I've seen quite a lot of CDs that do,
I'd even say that at least the early ones did it quite regularly).

Anyway, I'd certainly be interested to look into any CD that NetBSD doesn't
grok, if you wouldn't mind to lend it to me for a few days (albeit I don't
have NetBSD/amiga).
