> in 1.0 if a file was both in a jobs cache archives and cache files, and
> InvalidJobConfException was thrown. We should replicate this behavior on
> mrv2. We should also extend it so that if a cache archive or cache file is
> not going to be downloaded at all because of conflicts in the names of the
> symlinks a similar exception is thrown.
