The space allocation isn't intended to 'keep user-level program from filling up the disk', it's intended to allow the fragmentation-avoidance to work. Size doesn't matter; percentage does. I've heard somewhere (from Terry, I think) that 15% is the 'optimal' setting for this, and 10% was a compromise that wasn't too far below optimal, but gave that 5% of extra available space. 8% is the current default in newfs(8). -- 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-chat" in the body of the message
