Of course, I knew this would What ridiculous, unsubstantiated flame-bait. There are any number of options that you can turn on or off, and FreeBSD shipped with wc ON for a very long time without catastrophic effects. It's only for a very brief window in our history that we turned it *off*, and everybody and their uncle then screamed that we'd just seriously pessimized performance with no proof whatsoever that having it on had ever caused data loss. In areas where we're quite sure the opposite is true, like async filesystem mounts, the defaults are and will remain quite conservative. Besides, anybody who wants reliability from an IDE drive without some sort of hardware RAID assistance (like a 3Ware controller) has no clue about creating a "server-tuned OS" from the hardware perspective anyway, so this option is more or less irrelevant to them. The micky-mouse admins are just doing it as a hobby anyway so why take their ravings that seriously? You want a server, use SCSI drives at the very minimum and some sort of RAID product on top of that if it's really genuinely a server. The hardware's cheap enough now that there's simply no excuse for not taking such steps. Enough said. - Jordan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
