I think Kirk would know a thing or two about FFS. ;-) On Thu, Mar 29, 2001 at 04:53:55PM -0800, Bakul Shah scribbled: | Dumb question time. Why would I want to run a background | fsck on an active filesystem? One wouldn't mount an unsafe You want your system to be up as soon as possible.

This is a significant architecture addition/redesign to reduce fsck time. -- +-----------------------------------------------------------+ | keichii@iteration.net | keichii@freebsd.org | | http://iteration.net/~keichii | Yes, BSD is a conspiracy. | +-----------------------------------------------------------+ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
