Antoine Musso ee58c5b1cc debian-minimal: configurable debootstrap components
The debian-minimal element creates /etc/apt/sources.list solely with
the 'main' component. I need to add 'non-free' and 'contribs'. I tried
to pass them via DIB_DEBIAN_COMPONENTS but it is not recognized.

Make debian-minimal to honor DIB_DEBIAN_COMPONENTS. Note that it is
comma separated for 'debootstrap', so replace commas with spaces to fit
the needs of sources.list.

Example usage:

 DIB_DEBIAN_COMPONENTS='main,non-free,contrib'

Will debootstrap with the three components then when debian-minimal is
realized pre install a sources.list that has:

  deb http://example.org/debian jessie main contrib non-free

debian-minimal

Create a minimal 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.

By default only main component is used. If DIB_DEBIAN_COMPONENTS (comma separated) from the debootstrap element has been set, that list of components will be used instead.

Backports are included unless DIB_RELEASE is unstable.

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. It is also recommended that the 'debian-keyring' package be installed.

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_APT_KEYRING if that is used as well.

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.
