I am asking this because for rollback purpose this is essential difference, that package is probably kept <-- and --> is kept for sure 101%.

So you have to have some good luck, and be online -- which kills the purpose of rollback (how you rollback some net package, which establishes net connection).

I would like to not go that far.
All I need is simple rollback -- when I update something, it is stored, and that's all. Even after a year, if I need rollback, I rely totally on myself, not any third party, I simply install the package I have on disk. KISS principle at its best I think.

I think better approach would be to patch apt-get -- add an option which guarantees no package is removed during install, even if there is no space on disk (in such case download & install fails, but the old packages are intact). Since apt-get is open-source I think amount of coding is comparable, but in this approach the result would be rock-solid.

that the patch is not that hard -- because storing is already there. So such option would only prevent deleting. All it takes is -- adding an option, finding all references to cleaning the cache, and adding conditional in all places except explicit clean. That's all. Job well done, zero workarounds
