Hi Richard,

thanks for your feedback!

layers in yocto are like a core layer and a kde layer and then when you add 
a cups layer kde is build with cups support (and else not), or what are layers

If so I think it's yet something different (though more similar) to eg OpenWrt 
hich has different configurations and packages for different targets...

(more similar because iirc one can configure different libc implementation
on OpenWrt which will affect packages builds.)

or how would you describe this layer concept? :)

impressive list!
