My initial reaction to this description is that it "sounds reasonable". However, I guess I'm not sure what the head branch will be called after 5.0-release, and before we consider it "production quality". Presumably it will still be called -current, but it can't be the same kind of -current as it was before 5.0-release. *Some* things have to be considered frozen, or else 5.0-release is a meaningless datapoint. So, I have no problem with saying that kernel ABI's will not be frozen until 5.1-release, but I assume all the user-level ABI's and API's are considered frozen at 5.0-release. -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
