But there's nothing official to > distinguish whether a program uses FreeBSD or NetBSD shared libraries. I spent a little time talking about this with Mike Karels (BSDI) and Chris Demetriou (NetBSD). The conclusion was that shared library compatability was a false grail and should not be pursued. It's hard, it's easily broken (meaning you get stuck in this thankless loop of fixing it over and over again as the libraries themselvse change) and in the case of BSDI, a rather difficult target to hit anyway (they will have an entirely different shared lib strategy). I know it would be useful and make the users happy, but neither I nor anybody else I know is willing to sign up for the work involved so it's just better to assume it isn't going to happen. Jordan
