Yes, but many systems in the past did't have cpio.

And, my linux box doesn't seem to have it either.  I guess that's
a package I didn't install :-)

Lots used to not ship cpio, that's changed over time.

I'd prefer to just stick with tar/cpio between those two we should
have every significant unix covered.

I wouldn't object to removing the "B" from the tar options and then
removing cpio support -- I'm not aware of a system that doesn't ship
tar (then again, maybe you are :-)
