yes. it is why it isn't a simple problem in the general case. some users could rely on old files. > sysclean wasn't designed to delete these libraries, but these libraries > are the biggest win as far as diskspace, so the selection algorithm > started hoovering them up, and it seems semarie doesn't want to walk > back "OK, I can clean _other things_ but I must leave the libaries alone". > > Because then I guess then sysclean doesn't feel like such a winning > proposition at all... semarie@ spoke about integrating some elements inside the installer when he was about "clean _other things_". It isn't about "stepping back". Even if the installer would clean all it is possible to remove safely, I would still use a program to list libraries without registered packages using them. I wrote sysclean because it solves *my* problems regarding maintaining a system, and I shared it because it could help *some* others people. It wasn't created with intent to solve the general use case for all possibles users. My use case is I don't build local program without packages (and I created some "local" packages for personal stuff). So I know I could remove old libraries. I know the systems I am maintaing, so I know what I could remove or not. You don't like it, fine. Just don't use it.
