With this patch, /var/cache/apt/archives directory content is preserved. The directory is actually a bind mount of the ~/.cache/image-create/apt/$DISTRO_NAME directory, much like what we do for ccache. You can use DIB_APT_LOCAL_CACHE=0 to disable this behavior. This trivial change improve performance A LOT (>30%), even if a local HTTP proxy because: - there is no need to copy again and again the same files - we avoid network latency The patch has been tested with Debian and Ubuntu with every elements from the tripleo-image-elements repository, the final size of the cache directory is about 700MB per distribution subdirectory.
