Yes. The size of a symlink is supposed to be the length of the path the symlink is pointing to. > or is it just the way it worked out? (Or both?)

All dirs are given a size of 0 explicitely to circumvent a curious behaviour of the NTFS driver, see comment in fhandler_disk_file.cc, lines 527ff(*). Special device entries, local sockets or named pipes have a size of 0 even if the underlying file representing the device has not.
