Split the debootstrap functions into an element debootstrap is not debian or ubuntu specific. We can make a debootstrap element that knows how to do all of the things, and then a debian-minimal and ubuntu-minimal image that use it. Finally, make the debian element simply be a collection of the extra things we do to make it look like a cloud-init based cloud image. Change-Id: Iaf46c8e61bf1cac9a096cbfd75d6d6a9111b701e

Clear up debian element documentation There is some confusion in the readme's over what is happening. The original change (Iaf46c8e61bf1cac9a096cbfd75d6d6a9111b701e) split out debian-minimal and made debian "... simply be a collection of the extra things we do to make it look like a cloud-init based cloud image" Make this clearer in the documentation Change-Id: Ibe6fad9c67b70a5e31e43e06419968135174fef3

By default this element creates the latest stable release. The exact
setting can be found in the element's ``environment.d`` directory in
the variable ``DIB_RELEASE``. If a different release of Debian should
be created, the variable ``DIB_RELEASE`` can be set appropriately.
Semi-automatic doc generation of element dependency Currently there is no description of dependencies in the generated documentation of the elements: therefore a user of an element does not know which other elements are automatically included and e.g. which configuration options are available. In addition there are some copy&pastes of parts of the README.rst scattered thought different Ubuntu and Debian specific elements. This patch adds a semi-automatic generation of dependency information of all elements. Nevertheless these are not automatically included. The author of the element's README.rst can decide if and where the dependency information should appear and can use the descriptor .. element_deps:: for this. This patch adds the dependency information for some Debian and Ubuntu patches - and creates the base for later removing the duplicated parts. A call is added to element_dependencies._find_all_elements() to populate reverse dependencies for Element objects. (This is a reworking of I31d2b6050b6c46fefe37378698e9a330025db430 for the feature/v2 branch) Change-Id: Iebb83916fed71565071246baa550849eef40560b

Install systemd earlier for Stretch Debian Stretch released as stable recently, and the init system is less tightly specified in the base dependencies (for some info, see [1]). It seems, probably unintentionally, that in the previous release systemd-sysv was brought in by debootstrap, but that is no longer happening. Add systemd as an early dependency of debian-minimal. Remove the package-installs.yaml as that happens too late (other things need to know the init system to write out service files, etc and probe for systemd utils before package-installs). As mentioned, I do not believe the "only install systemd on testing" idea was actually working here, because it was being brought in during the initial debootstrap. Update some documentation to explain what's going on [1] https://lists.debian.org/debian-boot/2015/05/msg00156.html Change-Id: Id67c0cf08728407d234976f9807d3bd71d12f758

Add security mirror override for debian-minimal Add option to set the security mirror URL independently in the debian-minimal element, since this can not be overriden by the standard DIB_DISTRIBUTION_MIRROR variable. Change-Id: I145844a410d06a479e68db1bf6d5d0159389305c

The element obeys the ``DIB_DISTRIBUTION_MIRROR`` argument for
mirroring (see ``debootsrap`` element documentation). However, the
security repositories are separate for Debian, so we can not assume
they exist at ``DIB_DISTRIBUTION_MIRROR``. If you do not wish to use
the upstream repository (from ``security.debian.org``) override it
with ``DIB_DEBIAN_SECURITY_MIRROR``.
