I tried this solution:
   COMPLEMENTARY_GLOB[conf-pkgs] = '*-conf'
   IMAGE_FEATURES_append = " conf-pkgs"

But this did not work for me. The obvious reason(i guess) is no matching 
packages build for '*-conf', though all configuration recipes provides 
'<base_component>-conf' packages, but the dependency is missing to build 
those packages :(.

My layer provides configuration packages for core components, such as 
'connman', 'openssh', 'dropbear', etc., which needs to/can be configured 
with our configuration framework. I would like to find a way to pick the 
corresponding config packages based on the image configuration, for 
example 'openssh-conf' or 'dropbear-conf' whichever the image is 
configured to use.

Thanks,
Amarnath
