I noticed in debugging that with python3 all the pkg-installs output is preceeded by a b'foo', which suggests coding issues lurking. The universal_newlines argument makes subprocess readline() returns a decoded str (via locale) instead of a byte-string. This clears up a couple of points where we explicitly decode and cleans up the print output. Minor formatting cleanup of command and exit display. Don't strip the leading spaces so indents retain in the output Change-Id: I2894f10a0c2fc618563641b9d106b716f4a544aa
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: 3example 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.
