Actually, this is mentioned in the white papers of all journalling FSs, but is generally glossed over with application specific hardware that is missing on PCs, which will record the cause of the failure across a reboot, and will throw a chock in front of the wheels before a bad write on a power failure... something IDE drives fail to do, but SCSI drives do not (or did not, until recently). Of course, you can't just use PC CMOS for this because of the lack of DC hold up time and AC fail notification in standard PC power supplies. You owe the Oracle your first born child, and , because of the GPL, anyone who marries your first born child owes the Oracle their first born child, and so on, recursively and eternally, forever after. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
