This whole "soft dependencies" idea has been discussed to death numerous times already, and the conclusion has always been that they really don't solve anything. There is a wide range of very different functionalities under this idea: Suggestions for additional packages that might be useful for a tiny minority to packages that should be installed together always except if you are extremely tight on space, packages that work well together, packages that form a set with a common UI, ... > But I think everyone is in agreement that we need soft dependencies in > order to sort out our current dependency mess.

Then either the system services require too much "desktop" (bug to be fixed, has nothing whatsoever to do with soft dependencies) or the desktop is insinuating itself too much into the system (very little can be done about this, GUIs and desktops and ... _are_ the primary use of current systems, soft dependencies won't do anything about that tendency). > Soft > dependencies, together with dlopen() might be a good way of solving this. That doesn't solve anything, it just complicates applications (need fallbacks when something isn't available, need to handle oldish versions, ...) > Therefore I'm wondering: Are there any better ways of solving this File concrete bugs.
