I installed the latest version of cdrecord package (not cdrecord-current)
on my NetBSD15ZC system and ran

  mkisofs -l -L -N -o /tmp/isofs -r -v -v jpg/99????

When I burned a CD, I found that all files are in the root directory, and
the original directory tree was completely lost.  I was expecting to see
several subdirectories under jpg and the files in the subdirectories.

I believe I have used the same command line succesfully before to copy the
directory hierarchy to CD.

Is mkisofs broken or am I just blind (I have read the man page, but afaict,
this should work).

Thanks,
