One would hope so. All I remember about CDROMs is they use a different
blocksize which causes all sorts of funny side effects in generic code
that assumes the only sane blocksize is 512. Not having read l-k since '98
I missed that.

So mounting HFS CDROMs no longer panics? But there's been other reports of
HFS bugs I think. HFS could use a larger overhaul, that might make
integrating HFS+ easier and either do away with the 512 byte blocksize
assumption or hide the conversion inside the HFS driver.
I know nothing about filesystems in general, much less HFS. If there was
another informed discussion on l-k on this topic I'd be happy to know.
