We can do both, and it makes sense to do both. That is, we can have Issue 7 TC2 specify Option 2B with a suggestion to implement Option 2A, and have Issue 8 require Option 2A. > cpio may have a similar issue on overcounting. Good point; it's likely that many implementations of pax, cpio, and tar have problems in this area. I fixed this bug in GNU tar in 2010, here: http://git.savannah.gnu.org/cgit/tar.git/commit/?id=37ddfb0b7eb41cc3f58bce686d389b1e965e9ccf
