Firstly, I'd recommend you create your own custom image recipe(s) rather than 
adding packages via local.conf. Secondly, the way to handle bringing in a 
large number of packages as a unit is to create a packagegroup recipe within 
your custom layer to pull in all the packages you want installed, and then you 
just need to add that packagegroup to your image.

Cheers,
Paul
