Hi Richard,

Yes, the package contents may vary, but should this not be up to the 
distro to be able
to configure meta-packages with a common top-level api ?

I suppose we can create our own ALLOW_EMPTY meta-package recipes, where 
items are RDEPEND:ed,
which in turn mirrors the contents of selected IMAGEs.

DISTRO_FEATURES and in some degree PACKAGE_CONFIG also alters package 
dependencies,
and contents. I can't really see how this is different.

Br,
David
