[PATCH] archiver: exit to avoid race conditions


Jose Quaresma
 

The archiver doesn't support using multiconfig sharing the same TMPDIR
so rise an error when we have something that shouldn't exist.

When in the multiconfig and using the same TMPDIR: the two machines can make
the same copy at the same time to the same destination, which will not work.
