git repositories, distribution packages, or pip.
Many elements expose different install types. The different implementations
live under <install-dir-prefix>-<install-type>-install directories under an
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

To set the install type for an element define an environment variable
DIB_INSTALLTYPE_<install_dir_prefx>. Note that if you used '-' characters in
your install directory prefix, those need to be replaced with '_' in the
`DIB_INSTALLTYPE_<install_dir_prefx>`. Note that if you used `-` characters in
your install directory prefix, those need to be replaced with `_` in the
environment variable.
For example, to enable the package install type for the set of nova elements
that use `nova` as the install type prefix, define the following:
export DIB_INSTALLTYPE_nova=package
