Please review the following truss output. The bug (If it is indeed a bug)
seems to crop up with doing cp with the -Rf options, when copying files
that are the same atop one another. Although cp correctly identifies them
as identical, after that it unlinks the 'target' in preparation for a copy
that of course never happens, the end result being deletion of said file(s).
Output from cp --version:
