Hello
I want to add packages to my image using the local.conf file. 
For example
IMAGE_INSTALLED_append += " dmidecode i2c-tools"

Do I have to specify every package or is there a way I can add all packages inside a layer?
For example, how do I add all packages from inside poky/meta to my image? 
Or at least how do I add all packages under poky/meta/recipes-devtools ?

thanks
Madhu
