It seems to be a different issue. The problem with GNU tar is that it
issues a warning and exits with nonzero status, which is a problem for
backup scripts because they can't easily distinguish this case from an
actual failure. But AFAIK the output file is self-consistent anyway.
It sounds like bsd tar is just plain broken :-(
