I was not previously much aware of get/setfattr, but I agree that that looks
like a possible way to provide access to the Windows SYS attribute and friends.
Not that I am that familiar with details of what NTFS, etc., provide, getfattr
may be a way to provide access to additional attributes / facts about files
(paths, generally) as well.  Sounds like it would not be too hard to support
access to the basic attributes this way.

I suspect the general response will be PTC, though!  :-)
