Policies exist for a reason: suppose you're uninstalling the package for a db server, try imagining how fun it'd be to see the data thrown out. No, not for a broken db, any db!

If you believe that the Application Manager (i.e., the gui, not the package manager which is dpkg) should use --purge instead of --remove, try submitting a bugreport / brainstorm (but do check the current situation first!)

The decision to go with rpm for MeeGO has nothing to do with such small details, afaict.

Now, back to the original question... any news about a fixed version?
