Symlinks are implemented as files in Linux, we write the path into the file that you are pointing to, so there most certainly is data that must be fsync()'ed if you want it to be persistent. Edit: If you want to fsync the symlink you can do an open with nofollow iirc (on my phone so I can't check) so you get the actual symlink and not its target.
