Ahoj!
Just select packages from Repository @System, and then as a secondary filter select "Unmaintained", and you will see all packages not available in any repository, but installed.
It reminds me: out of nowhere, suddenly @System appeared in the list of known repositories in (all?) package selectors. According to Jano (jkupec), it represents local RPM database. I was thinking about removing it from repository list (because it is not 'real' repository, with name&URL, or am I misunderstanding something ?), but now I have doubt - is it really supposed to stay there? What is its purpose?
In case Katarina or Ricardo want to mimic this, it is pretty easy, as once you have installed packages
Hmm ... I'm afraid I cannot add 'secondary filter' to ncurses PS (ENOSPACE :) ). So I'm thinking about adding 'Unmaintained packages' entry to the list of all available repositories. So I suppose it is OK to iterate the pool and find selectables that have isUnmaintained flag set ... B. -- \\\\\ Katarina Machalkova \\\\\\\__o YaST developer __\\\\\\\'/_ & hedgehog painter
