[Bug 1095588] [NEW] Storing extended informations of recommends

[Sworddragon]

Public bug reported:

I'm using Ubuntu 13.04 dev with apt 0.9.7.6ubuntu6. In the attachments
is an example where I installed brasero and wanted to remove it with all
the dependencies that were installed shortly before. The summary: I had
to install 35 new packages including brasero and on removing brasero and
doing an autoremove apt removed only 22 packages. Now there is the
question why the 13 packages are not removed but I know already the
answer. The 13 packages installed as a dependency by brasero are seen as
a recommended package of another package for apt. This is a big problem
because it makes it nearly impossible to keep the system clean. But
there is a simple solution to solve this problem:

apt has just to store more informations about the package states on
installing. Just an example: Every time a package is installed (even if
it is already installed) apt stores a list for every package which will
be successfully installed or is already installed and is a recommended
package about the package which installed it. With such a list apt-get
autoremove can calculate if there are any manual packages which have
installed recommended packages. If not the recommended packages could be
removed too.

Keep in mind that this is just an example. Maybe this can be optimized
to handle this better.
