The "do-release-upgrade" tool in Ubuntu has for some time had a
'sandbox' feature for upgrading from one release to another. This
isn't exactly what you're asking for (package by package upgrades and
rollbacks) but it's related.
It was designed so that you could (for example) attempt to upgrade
from 11.10 to 12.04, and it it all went horribly wrong, roll back to
11.10.
We now do automated testing of upgrades using various scenarios in
order to improve reliability for users. The results are publicly
available on our jenkins instance.
