I've done this before by creating a pair of recipes, let's say
'image-target' and 'project-target'. You would run 'bitbake
project-target' instead of 'bitbake image-target' to start the build.

* image-target is a normal image recipe including everything you want
  in the rootfs

* project-target DEPENDS on image-target as well as every other package
  you want to be available in the package feed

I'm not sure if there are any extra steps you need to take to update an
RPM package feed though, I usually work with ipk packages.

Thanks,
Paul
