Argh! My mistake! I really meant lstat(), not fstat(). Sorry.
However, I think that aufs actually got into a corrupted state where it returned st_size=0 for both symlinks and regular files. So, lstat(), fstat() and stat() all return zero. When this happens, "du" will return zero for a whole directory tree, but will give reasonable estimates with the "--apparent-size" flag. The next time it happens, I will try to get more details.
