Prior to 9.99.37 we have:
$ ls -li /bin/tar /bin/pax /bin/cpio
13081639 -r-xr-xr-x 3 root wheel 166288 Jan 12 17:00 /bin/cpio
13081639 -r-xr-xr-x 3 root wheel 166288 Jan 12 17:00 /bin/pax
13081639 -r-xr-xr-x 3 root wheel 166288 Jan 12 17:00 /bin/tar
Hardlinks; in 9.99.37 we have:
~ ls -li /bin/tar /bin/cpio /bin/pax
181767 -r-xr-xr-x 1 root wheel 50288 Jan 14 03:10 /bin/cpio
181784 -r-xr-xr-x 1 root wheel 166288 Jan 14 03:57 /bin/pax
181796 -r-xr-xr-x 1 root wheel 82352 Jan 14 03:10 /bin/tar
different files, but pax is the same as on 9.99.36, at least sizewise.
So the easiest way to sort oneself out of this is to hard-link
/bin/pax to the others and carry on the update.
