I've seen something in a couple comments now to this effect, does nobody here do anything with ZFS at all? It's a pretty great filesystem on not just illumos but FreeBSD, Linux, and macOS, and it has full native normalization support (and for all 4 forms too). Normalizing is optional, but it's definitely there and with Macs I have been using NFD for compatibility purposes for 5 years now with no discernible performance problems in day-to-day use. I know ZFS isn't remotely a majority but I don't think it's that obscure either.
- cryptonector 9y agoThank you for pointing this out. In particular ZFS has normalization-preserving/normalization-insensitive behavior, which is far superior to HFS+'s opinionated normalization-on-create (to a form that is different from the common input modes' output!).
- jorangreef 9y agoYes, HFS+ implements normalization-insensitive behavior through not being normalization-preserving, in the same way that some FATs might implement case-insensitive behavior through not being case-preserving. They didn't realize that you could have both features: normalization-preserving and normalization-insensitive.
- cryptonector 9y agoI guess it was a very forgivable lack of imagination. When we came up with form-preserving/insensitive we were motivated in great part by the interop mess caused by HFS+ -- we might not have arrived there without that mess, though I'd like to believe that someone would eventually have reached this conclusion regardless.
