I'm not sure I'm happy about DIAGNOSTIC; unless changed, it significantly change some codepaths, and it produce output about system state, not just extra checks. Any plain checks that are under DIAGNOSTIC is there through a miscommunication or not finished conversion, anyway; it should only be causing extra debug output. Adding the rest of them are in my opinion a good thing. Eivind. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
