For our Freifunk-build we do a similar 2-step thing

* using a .config having all pacakges added modular and only the packages
for the initrd set to "y" to have them embedded
* doing a normal build produces the initrds and the imagebuilder
* with the imagebuilder we generate the final sysupgrade images with the 
full package-set

The generated initrds are just a luci-mod-failsafe wich allows flashing the 
sysupgrade via browser and of course console.
