That is, if they want to interoperate. As you noted not long ago, it is a serious problem if an HFS+ partition is shared over NFS. If you look at all the apps that have problems with this aspect of HFS+ , they are all apps that transfer files over the network over diverse protocols. That's why it's a problem with git, because the files may be coming from a different machine, running any arbitrary OS that git supports. In such scenario, can you understand why everyone is saying that HFS+ and the VFS should not mangle names, even if it makes sense to some use cases under OSX? And do you understand why the same applies to git, being a network-sharing-oriented app? So -- if OSX was doing things to make it easier for users to find matching files at the Finder level, that'd be _fine_. But the FS has to deal with a lot more variety than that. So this is a bad design decision -- perhaps less obvious under OS8/9, but completely disastrous with a network OS such as OSX. Call it "different" if you want, but that's a euphemism for "wrong". cheers, m
