Well, I certainly agree. I have this situation. I have a separate build
system, which setups an overlay per device (3x mt7621 boards) in files and then 
also  does some post-processing to the rootfs via a change I put in the end
of the OpenWrt scripts. But one solution here might be per-target
package selection - I can imagine this getting messy though.
