When reporting bgfsck/snapshot/... problems, you may want to CC Kirk McKusick <kirk@mckusick.com> -- I don't believe he closely tracks current@, and he's the best person to track down and fix problems in this area. I forwarded your earlier message to him, but haven't heard back as yet. Just FYI. Robert N M Watson FreeBSD Core Team, TrustedBSD Projects robert@fledge.watson.org Network Associates Laboratories
