I was going through the list of packages installed in the image (as per the manifest file).
I noticed that metadata information for these packages is present at -
/build/tmp/sysroots/NAME/pkgdata/runtime/

Now I do notice that rarely for a few packages mentioned in the manifest list, the corresponding metadata file is not present here.
Also sometimes, though the file is present, it says “PKGSIZE_pkgname: 0”
Example: PKGSIZE_packagegroup-base-ipv6: 0

What are these 0 size packages that manifest says are part of the image?

They're called metapackages: they exist as packages but don't actually install any files.  They're used to pull in other packages through dependencies.  packagegroup-base-ipv6 is a bad example as it actually only pulls in one other package, but packagegroup-base-bluetooth is a good example as installing that causes about 15 kernel module packages to be pulled in (to enable bluetooth support).
