[Bug 70098] Re: mkisofs doesn't properly convert lower case filenames to upper case

[enyc]

I have noticed exactly the same problem, when making CD images to use in dos/windoze-9x in qemu. As far as I can tell, the mkisofs in dapper works fine. I have been successful in using the dapper mkisofs binary (installed as /usr/local/bin/mkisofs.dapper) on an edgy system as a workaround for now.
All the same, edgy mkisofs in definitely broken -- almost as if it has -relaxed-filenames enabled when this has not been specified. I also notice that setting iso level 1 explicitly still does not fix the problem.
