It it possible to use Linux hardlinks?

I have not found any documentation the explicitly states that it either is supported or is not supported.

@jpandre THX a lot for testing this :-) Could you please add the mounting options that you have used to have a fully reproducible example?

It would be great if one of the developers could confirm that hardlinks are fully supported (or describing the known limitations).

@aryoda If you're looking for documentation, it's described in the very first section of the ntfs-3g manpage:

DESCRIPTION
       ntfs-3g is an NTFS driver, which can create, remove, rename, move
       files, directories, hard links, and streams; it can read and write
       files, including streams, sparse files and transparently compressed
       files; it can handle special files like symbolic links, devices, and
       FIFOs; moreover it provides standard management of file ownership and
       permissions, including POSIX ACLs.

No special options are needed, they are always enabled.

May I suggest to add a full list of supported features to the readme.md - maybe similar or in sync with the above cited man page - so that it is easier to find this information (without the need to install ntfs-3g first)...

Eg. hard links are not mentioned there currently...
