Because I didn't make cdboot's lookup routine handle symlinks.  It
also doesn't look at Rock-Ridge extensions and only uses the base
ISO-9660 directory entries.  That was enough fun to write in assembly.
OTOH, CD sectors are 2k, so you do have that much room to work with
and can probably fit a more advanced directory lookup into cdboot.

I'm happy to review any patches you come up with.
