Sorry, I guess I didn't see what you were getting at. Actually, this sounds like pretty useful feature, as +REQUIRED_BY doesn't list a package that depends on itself. In any case, this still doesn't provide enough protecion against accidental erasure. The specific case: deleting a dependent package that the user may want to keep, yet never explicity installed it or flagged it. It's a fact that people will use some programs that are installed for them by automata. How would you make the system aware of which programs these are, before deleting them? There would probably need to be some mechanism to get the user's permission first. --Allan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ports" in the body of the message
