What's going on is that in ISO images, long names get split up across
multiple directory entries, and makefs creates duplicate directory
entries when two files or directories have names that differ only after
the first 32 characters.  This started occurring when we started
including wifi firmware packages on DVD1; some of them (and hence some
of their directories under /usr/local/share/licenses) have very long
names that differ only at the end.  It doesn't seem to bother libarchive
or our own cd9660 implementation, but it bothers pycdlib.  I wasn't able
to get to the bottom of it (is makefs at fault, or pycdlib?) but I did
create a pycdlib port to facilitate further investigation.
