And what about cleanstate or cleanall?

What I want to do is be certain that I am in the exact state that I would be in if I had made a clean checkout and then build from scratch.

The particular case that made me ask was that I added BB_GENERATE_MIRROR_TARBALLS = "1" to local.conf and wanted to trigger doing that.  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).

Many thanks,
Tom
