Right and I think the kernel configs being added here only affect meta- intel as well. So people already using meta-intel, if they are concerned about disk footprint, would likely have to fine tune other things as well besides the kernel. > > That excess is the price meta-intel pays for trying to support > "everything" and behaving more like a desktop distro would.

I assume that they will tweak the kernel config and/or the software being enabled and installed for their use case and product using the various ways YP is good at. meta-intel provides a reference or a starting point in my opinion that is tested by us on a wide range of hardware.
