Right. If you are defining the requirements for a new FS on a new OS, would you not include a requirement that says "must not add any funny rule that prevents clean interoperation with other filesystems or OSs"? Forgetting that requirement is... a big one! And if someone asks "how do we do nice user-friendly filename matching with these technical differences that users mostly don't care about"... wouldn't you say "do it in the GUI facilities, changing the FS to handle this is wrong because it will break the OS as a server, as a reliable file storage"? FSs have pretty hard requirements these days -- all the modern FS you've heard about respect the requirement above, and a ton more that you have to be in the FS business to be aware of. Mostly anyway, wherever they don't, users have all sorts of trouble. > IIRC, the biggest problem he talked about was the changing unicode standard, > but since the technote appears to state that HFS+ will not be changing its > normalization algorithms to preserve backwards compatibility with existing > volumes, that doesn't appear to be a nasty issue after all.

Well, Ted answered that part, noting that then the "normalisation" is patchy, and everyone else is left to guess what chars are normalised and what chars aren't so being HFS+ compatible becomes a very weird game indeed. You didn't reply to his explanation -- you called him arrogant instead. Did you manage to read to the end if his email? The HFS+ designers mucked it up -- and then papered over it with the OSX libraries. But a good chunk of the world does not use them, they forgot about the little "interop" requirement. cheers, m - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
