In our project we mix the usage of volatiles, symblic links and unionfs.
You can take a look into https://github.com/rehsack/meta-jens (or
https://github.com/rehsack/yocto-builddir/tree/master/conf for other
used layers) to get a picture.

All used utilities for basic results (minimal image ...) like mkimgs,
flash-device.sh for burning mmc's from nfs boot etc. are included.

I think that should work with branches before daisy as well.

Good luck
