Sure but that is easily addressed. How does emerge know a package is in system profile or a set? Similar methods or others can be used to determine if a user installed a package. In a clean scenario, with a world file that ONLY contains stuff the user merged directly. Then emerge could simply check that file, against the stuff it already checks now. Is it in system? Is it in a set? Is it in world? If no to all, its a dep, warn! It is really NOT complex, nor does it require complex depgraph or any of the function of --depclean/-c. Thus I say once again, mentioning anything to do with depclean is not relevant and side tracks the discussion. There is no need. If you did want to actually see if any deps existed. All you need is to see if there is 1 installed package that needs the one a user is trying to install. No need for a complete depgrah etc. There are several ways to go about this that are not complex. -- William L. Thomson Jr.
