[Bug 1069902] [NEW] packages-to-remove dialog should allow user to toggle exceptions

[Christoph Buchner]

Public bug reported:

I think this is the right package to report this feature request
against. I also searched update-manager bugs but couldn't find a
duplicate.

On upgrading Ubuntu, after the new packages have been installed and
configured, the user is presented with a dialog offering a (typically
great) number of "old/obsolete" packages, and the only options are to
either "Keep" or "Remove" them all.

Normally, it's a good idea to remove the old packages. In the case that
the user wants to remove all of them except one, because whatever
algorithm is behind this has a false positive, or for some other reason,
this is not possible - it's either keep them all, or remove them all. It
would be great if the list of packages had checkboxes where you could
exempt certain packages from being kept/removed.

(In my case, on upgrading from Precise to Quantal, I would have liked to
keep a self-installed package of an old/unmaintained  application -
bouml - that the release-upgrader wanted to remove.)
