So how would I explicitly tell "I want hardlinks for everything else, but use cp when going between /usr/bin and /usr/libexec" (because /usr/bin and /usr/libexec is not on the same filesystem on this particular box---I'll tell you to use hardlink everywhere on another box of mine where they reside on the same filesystem)? Your argument or analogy with openssl does not make much sense to me in this case.
