Wow, quiet in here.
FOG, aka Free Open Ghosting, at www.fogproject.org, will certainly take images of your hard drives; that's not a problem.
And, I haven't played with it, but it has the capability to do install packages, so that meets the bit-by-bit portion of things.
Like most open-source packages, FOG improves constantly, and recently, it's getting better by leaps and bounds.
