The dib-run-parts element was copying our internal version of dib-run-parts into /usr/local/bin to be used running scripts inside the target chroot. However, it never cleaned up after itself. This means all images were left with an unmanaged local install of dib-run-parts. This copies dib-run-parts into the hooks directory of the chroot and runs it from there. It is cleaned up automatically on the exit path. The dib-run-parts element is no longer required and it has been removed from all dependencies. It is left with a deprecation notice in the README. For compatability we convert it to simply install dib-utils. Codesearch shows no users depending on this unintentional implicit install. Note os-refresh-config depends on dib-utils and thus will have an explicitly installed version. Partial-Bug: #1673144 Change-Id: Ia2e96c00a4246c04beb96c17f83b8aefb69219ca
debootstrap
Base element for creating minimal debian-based images.
This element is incomplete by itself, you'll want to use the debian-minimal or ubuntu-minimal elements to get an actual base image.
If necessary, a custom apt keyring and debootstrap script can be supplied to the debootstrap command via DIB_APT_KEYRING and DIB_DEBIAN_DEBOOTSTRAP_SCRIPT respectively. Both options require the use of absolute rather than relative paths.
Use of this element will also require the tool 'debootstrap' to be available on your system. It should be available on Ubuntu, Debian, and Fedora.
The DIB_OFFLINE or more specific DIB_DEBIAN_USE_DEBOOTSTRAP_CACHE variables can be set to prefer the use of a pre-cached root filesystem tarball. Setting DIB_OFFLINE may cause other element to use cached data, while DIB_DEBIAN_USE_DEBOOTSTRAP_CACHE only functions in the debootstrap element.
The DIB_DEBOOTSTRAP_EXTRA_ARGS environment variable may be used to pass extra arguments to the debootstrap command used to create the base filesystem image. If --keyring is is used in DIB_DEBOOTSTRAP_EXTRA_ARGS, it will override DIB_APT_KEYRING if that is used as well.
The DIB_DEBOOTSTRAP_CACHE variable can be used to cache the created root filesystem. By default this is 0 (disabled) and any other value enables this. If run in offline mode then the most recently cached rootfs is used instead of being built.
The DIB_DEBOOTSTRAP_DEFAULT_LOCALE environment variable may be used to configure the default locale of the base image. It defaults to C.UTF-8.
Note on ARM systems
Because there is not a one-to-one mapping of ARCH to a kernel package, if you are building an image for ARM on debian, you need to specify which kernel you want in the environment variable DIB_ARM_KERNEL. For instance, if you want the linux-image-mx5 package installed, set DIB_ARM_KERNEL to mx5.
