We support building elements without depending on the base element. Breaking install-types out into its own element while making base depend on it so elements can depend in it without base. Change-Id: I104543d5482c76f60902e9fc32d91e196eeab51a

Enable install-types support for elements.
|
|
|
|
Install types permit elements to be installed from different sources, such as
|
|
git repositories, distribution packages, or pip. The default install type
|
|
is 'source' but it can be modified on the disk-image-create command line
|
|
via the --install-type option. For example you can set:
|
|
|
|
--install-type=package
|
|
|
|
to enable package installs by default. Alternately, you can also
|
|
set DIB\_DEFAULT\_INSTALLTYPE.
|
|
|
|
Many elements expose different install types. The different implementations
|
|
live under `<install-dir-prefix>-<install-type>-install` directories under an
|
|
element's install.d. The base element enables the chosen install type by
|
|
symlinking the correct hook scripts under install.d directly.
|
|
`<install-dir-prefix>` can be a string of alphanumeric and '-' characters, but
|
|
typically corresponds to the element name.
|
|
|
|
For example, the nova element would provide:
|
|
|
|
nova/install.d/nova-package-install/74-nova
|
|
nova/install.d/nova-source-install/74-nova
|
|
|
|
The following symlink would be created for the package install type:
|
|
|
|
install.d/74-nova -> nova-package-install/74-nova
|
|
|
|
Or, for the source install type:
|
|
|
|
install.d/74-nova -> nova-source-install/74-nova
|
|
|
|
All other scripts that exist under install.d for an element will be executed as
|
|
normal. This allows common install code to live in a script under install.d.
