I don't get how tagging will help keeping your package list as small as possible. Let me give an example: We have 2 packages, Y and Z that were explicitly installed and are tagged accordingly. Y has A, B and C as dependencies. Z has C, D and E as dependencies. The dependencies of course are not tagged, right? Or if they do get marked they get a dependency tag(redundant). Now, as far as I understood you want to achieve the following. If you want to uninstall Y you want to keep any dependencies that were explicitly installed. But, what about A, B and C? They are not tagged as explicitly installed. Which means that either you won't delete any of them, or delete all of them and break the installation of Z since C is going to be missing. Please give me an example of your tagging methodology/plan so we can get an overview of the functionality you have in mind. Thinking of it a bit more, here is a potential solution. You install C which is a dependency of Y. C is marked as "explicitly installed". Later on, you install Y and it is also marked as explicitly installed. A and B are installed as dependencies. Now, you decide to remove Y with pkg_delete(1). It should get the list of dependencies, A, B and C, remove the ones that are marked as explicitly installed, thus removing C from the dependency list, and then uninstalling the ones that are not needed from any other package currently installed on the system, that is A and B. How about that? -- Sideris Michael http://black.daemons.gr/msid/
