Adds support for post-install scripts. Post install scripts are useful because they can perform tasks you want to handle after the OS/application install but before the first boot of the image. e.g: Clean the cache left by the package manager reducing the size of the image.

set -u and -o pipefail everywhere As with the previous similar changes, this is intended to catch problems as they happen instead of ignoring them and continuing on to potentially fail later. Setting this on all existing scripts will allow us to enforce use via Jenkins. Change-Id: Iad2d490c86dceab148ea9ab08f457c49a5d5352e 2014-04-03 02:24:15 +00:00			`set -eu`

dpkg: local cache for .deb files 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.
