Does ext2fsd support creating hardlinks? The reason I'm asking is that Cygwin does not create hardlinks out of the blue. It certainly doesn't communicate with a driver directly. It just calls the underlying system call NtSetInformationFile(FileLinkInformation). If that doesn't work, neither Cygwin nor any other Windows applications have a chance to create a hardlink. Alternatively, does the CMD.exe `mklink /h' call work? If so, ext2fsd requires another set of flags to create hardlinks than NTFS, apparently.
