Only if the file system doesn't preserve case. Most modern
case-insensitive file systems (FAT, NTFS, HFS) preserve case. CIOPFS
preserves case if it's allowed to write xattrs to the underlying FS.
This is why I even had the case-preserving handling in there in the
So, if I understand correctly, you think that, if we determine that file
system is case-insensitive, we should also assume it doesn't preserve
case. Is that correct?
