--- Comment #1 from Erich E. Hoover erich.e.hoover@gmail.com --- I had this working at one point where FILE_FLAG_OPEN_REPARSE_POINT gets translated into O_SYMLINK (O_NOFOLLOW | O_PATH), I'll have to see what went wrong.
If I may ask, what are you using symlinks for? (I want them to eventually reduce the space consumed by the prefix, but getting them upstream has been a challenge)
