All of my (ufs) filesystems are running with softupdates, except /. I've got plenty of free space on it, but: /dev/da0s1a on / (ufs, local, synchronous) /var, /usr, /tmp, etc are all on their own filesystems (/tmp is newfs'd on boot, too; THAT's how you avoid cleaning race conditions ;), so the only time writes happen on it is when I installworld or edit something in /etc; either way, I like knowing it's there when it says it is. Of course, it does slow the installworlds down to an astonishing degree. -- Matthew Fuller (MF4839) | fullermd@over-yonder.net Unix Systems Administrator | fullermd@futuresouth.com Specializing in FreeBSD | http://www.over-yonder.net/ "The only reason I'm burning my candle at both ends, is because I haven't figured out how to light the middle yet" To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
