In-Reply-To: Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Are you saying there's some tool that does the job right while the system is active? If so, please let us know! Otherwise, my statement is correct. That I didn't mention what should be common knowledge doesn't mean I wasn't aware of it. In fact, having to have the system down to do the post-installworld dump is part of the problem. If you don't back the system up, the buildworld/installworld path isn't to bad. But I rely on my systems for my livelyhood, and am not willing to put my data at risk that way.
