You're dating yourself here, Jim.  GNU tar is
over 20 years old.  ;-)  I also thought gnu tar
shipped with FreeBSD 1.0 in 1993, though I might
be wrong about that.

Sad but true.  The discussion in the Single Unix
Standard rationale about the design of the "-p"
option for pax should be required reading for
anyone interested in the design of archivers.

Unfortunately, an awful lot of build scripts
for various ports rely heavily on arcane details
of gnu tar behavior.  A lot of stuff would break
if bsdtar didn't at least make an effort to
follow GNU tar command-line conventions.
