Fixed: * The os.link() reqiures write permission on the src file (suppose the src file belongs to another user, then you need write permission to harlink to it since the link count would change) * Print more info when failed to copy The warning was like: WARNING: Could not copy license file COPYING: [Errno 1] Operation not permitted We couldn't know which recipe print the warning from this message.
