2.4.2.2. Build History Image Information

The files produced for each image are as follows:

build-id: Human-readable information about the build configuration and metadata source revisions.
*.dot: Dependency graphs for the image that are compatible with graphviz.
files-in-image.txt: A list of files in the image with permissions, owner, group, size, and symlink information.
image-info.txt: A text file containing name-value pairs with information about the image. See the following listing example for more information.
installed-package-names.txt: A list of installed packages by name only.
installed-package-sizes.txt: A list of installed packages ordered by size.
installed-packages.txt: A list of installed packages with fuill package filenames.

Note

Installed package information is able to be gathered and produced even if package management is disabled for the final image.

Here is an example of image-info.txt:

     DISTRO = poky
     DISTRO_VERSION = 1.1+snapshot-20120207
     USER_CLASSES = image-mklibs image-prelink
     IMAGE_CLASSES = image_types
     IMAGE_FEATURES = debug-tweaks x11-base apps-x11-core \
        package-management ssh-server-dropbear package-management
     IMAGE_LINGUAS = en-us en-gb
     IMAGE_INSTALL = task-core-boot task-base-extended
     BAD_RECOMMENDATIONS = 
     ROOTFS_POSTPROCESS_COMMAND = buildhistory_get_image_installed ;   rootfs_update_timestamp ;  
     IMAGE_POSTPROCESS_COMMAND = buildhistory_get_imageinfo ; 
     IMAGESIZE = 171816

Other than IMAGESIZE, which is the total size of the files in the image in Kbytes, the name-value pairs are variables that may have influenced the content of the image. This information is often useful when you are trying to determine why a change in the package or file listings has occurred.
