Create an image based on Debian. We default to unstable but DIB_RELEASE is mapped to any series of Debian.

Note that the default Debian series is unstable, and the default mirrors for Debian can be problematic for unstable. Because apt does not handle changing Packages files well across multiple out of sync mirrors, it is recommended that you choose a single mirror of debian, and pass it in via DIB_DISTRIBUTION_MIRROR.

If necessary, a custom apt keyring and debootstrap script can be supplied to the debootstrap command via DIB_DEBIAN_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.

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_DEBIAN_KEYRING if that is used as well.
