I don't have time to reboot into Linux right now, but on OpenBSD it
complains bitterly that it can't gzip while appending, and refuses to do
anything.

Leaving off the "z" option and working with straight .tar files works
great.

If that's the case for the tar you're using then you'll have to
decompress, append, then recompress.
