[yocto] Package relation between package.manifest and license.manifest

[Hugo Heutinck]

Question: What is the relation between the package.manifest and
license.manifest ?

After a yocto poky based image has been built there are 2 files in the
licenses directory "tmp/deploy/licenses/*image_name-datestamp*"

One is the package.manifest, which if understood correctly is a list of all
packages included in the image.

The second file is the license.manifest, but this one contains besides the
package name also the version, recipe name and license of the package.

However if I compare the package names in both lists, there seem to be a
number of packages in the license.manifest that are not part of the
package.manifest. E.g. "readline, popt, expat, freetype".

Is the license.manifest a list of all items in the package.manifest +
?build dependencies? or something ?

Regards,
