Create docs site containing element READMEs We currently do not have the ability to create a docs site which outlines all the elements. Change-Id: I77ccf61e0c4b1509b3e7ce9b8f15ea5ccfd50d9b

Move initial root contents into a hook. This is a necessary but not complete step towards supporting Fedora and Suse distributions. Further work is needed (e.g. to quiesce daemons on installation). Change-Id: If3ea6093d41a21de755db52328226b84b5a3ede6

Use Ubuntu cloud images as the baseline for built disk images.
Migrate cloud image URL/Release options to DIB_. This switches $CLOUD_IMAGES and $RELEASE to the DIB_ namespace so they will survive future changes to the sanitisation of the build environment. Change-Id: I7dc2aa82fb9ef452705b080cc404f41046014f20

Overrides:
* To use a non-default URL for downloading base Ubuntu cloud images,
use the environment variable DIB\_CLOUD\_IMAGES
* To download a non-default release of Ubuntu cloud images, use the
Set DIB_RELEASE in ubuntu element The other distro elements set DIB_RELEASE which allows the other elements to know what distro release is being built during the extra-data or environment.d phases. Change-Id: I00bf13410ded5b678ebc66ff191891ed3cc80f4f

environment variable DIB\_RELEASE. This element will export the DIB_RELEASE
variable.
Replace security.ubuntu.com when setting mirror The current method to rewrite the mirror URL in the ubuntu element will only rewrite archive.ubuntu.com, which leaves the security URL alone. This is probably not intended for people who are creating images behind firewalls. Change-Id: I54a867e0e9d5a7c94324a5c00ff1a83b4e6e4524

* To use different mirrors rather than the default of archive.ubuntu.com and
security.ubuntu.com, use the environment variable DIB\_DISTRIBUTION\_MIRROR
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
