For those who don't know about it:

pax now has capability to set the permissions (for the files in the
created archive file) using mtree specifications. (Thanks to L. Mewburn.)

For example, my destdir's passwd(1):

-r-xr-xr-x  2 reed  src  17800 Nov 19 12:08 usr/bin/passwd

Then the METALOG file (built via the build.sh script) used by the
pax to create a tarfile contains:

./home/src/usr/bin/passwd type=file mode=04555 uname=root gname=wheel

So software in the tar sets can be setuid root. Now extracting and
preserving this info must be done as root.
