  clean : roughly the same as removing tmp
  cleansstate : roughly the same as removing tmp and sstate-cache
  cleanall : roughly the same as removing tmp, sstate-cache and downloads

Then remove tmp, sstate-cache and downloads. To be certain, remove
your build directory too.

There's not usually any need to do this kind of thing though (apart
from as a learning exercise).

The fact that just running bitbake <imagename> didn't do it made me paranoid about what other changes I might make that wouldn't get picked up, so I want to know how to roll back to set points in the build process and build from there (eg: clean, cleanstate, cleanall and any others that you can tell me about).
