I see FreeBSD tar(1) does support pax. I hadn't caught that yet... I
guess I need to catch up on my FreeBSD reading. I did try to use the pax
format with FreeBSD pax just in case it wasn't documented. It didn't
work. Too bad. At least the FreeBSD pax(1) man page and actual features
agree.

This was very helpful. I hadn't found the cross reference to
libarchive-formats(5) yet.
