I have implemented such a system with just some bash scripts and grep,
sed, dpkg-scanpackages, &c. I keep archives of all the .debs on my
machine in case I need to rollback, but snapshot.debian.net also
provides this.
I've posted these script a bunch of times.
Most of my scripts and programs I write are ultra-hackish and only
really work for me, but, who cares, I have a snapshot/rollback system
that gets the job done for me. That's what Debian's all about.
