package-installs

The package-installs element allows for a declarative method of installing and uninstalling packages for an image build. This is done by creating a package-installs.yaml or package-installs.json file in the element directory.

In order to work on Gentoo hosts you will need to manually install dev-python/pyyaml.

example package-installs.yaml

libxml2:
grub2:
  phase: pre-install.d
networkmanager:
  uninstall: True
os-collect-config:
  installtype: source
linux-image-amd64:
  arch: amd64
dmidecode:
  not-arch: ppc64, ppc64le
lshw:
  arch: ppc64, ppc64le
python-dev:
  dib_python_version: 2
python3-dev:
  dib_python_version: 3

example package-installs.json

{
"libxml2": null,
"grub2": {"phase": "pre-install.d"},
"networkmanager": {"uninstall": true}
"os-collect-config": {"installtype": "source"}
}

Setting phase, uninstall, or installtype properties for a package overrides the following default values:

phase: install.d
uninstall: False
installtype: * (Install package for all installtypes)
arch: * (Install package for all architectures)
dib_python_version: (2 or 3 depending on DIB_PYTHON_VERSION, see dib-python)

Setting the installtype property causes the package only to be installed if the specified installtype would be used for the element. See the diskimage-builder docs for more information on installtypes.

The arch property is a comma-separated list of architectures to install for. The not-arch is a comma-separated list of architectures the package should be excluded from. Either arch or not-arch can be given for one package - not both. See documentation about the ARCH variable for more information.

DEPRECATED: 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.

Using post-install.d for cleanup

Package removal is done in post-install.d at level 95. If you a running cleanup functions before this, you need to be careful not to clean out any temporary files relied upon by this element. For this reason, generally post-install cleanup functions should occupy the higher levels between 96 and 99.
