Why is your packing software trying to package something into a read-only directory? Why aren't you building it with something like "mock" or "koji", that will create use a clean build environment at /var/cache/mock/ without localized modifications? I can understand that your working environment might have "/opt/" or other network mounted directories set up with read-only permissions. But writing to such a directory at build time is begging for difficulty. I'd urge you to use "mock" or "koji" and keep your software building out of the working environment of the build server itself. That way lies booby traps.
