diskimage-builder/elements/package-installs/README.rst

The package-installs element allows for a declarative method of installing and
uninstalling packages for an image build. Adding a file under your elements
pre-install.d, install.d, or post-install.d directories called
package-installs-<element-name> will cause the list of packages in that file to
be installed at the beginning of the respective phase.

If the package name in the file starts with a "-", then that package will be
removed at the end of the install.d phase.
Support declarative package installs/uninstalls Adds a new element, package-installs, that provides an interface for declarative package installs and uninstalls. Packages to install can be added to an install.d/package-installs-<element-name> file. The set of packages listed across such files are installed in a single transaction at the beginning of install.d. Prefacing the package name with a "-" indicates that the package should be uninstalled at the end of the install.d phase. Again, the full set of uninstalls are done in a single transaction. An element providing a package-installs file should add package-installs to its element-deps file.

package-installs for pre-install.d/post-install.d Packages are often also installed in both the pre-install.d and post-install.d phases. This patch expands the package-installs element to support declarative package support for these phases in addition to the existing support for install.d. The actual install/uninstall logic is moved to common scripts under bin/ so that it can be reused across the different phases.
