Also point out the reliability factor here which is a bit harder to point to a magic number and "See, we *are* better!" ext2 runs async by default which can lead to nasty filesystem corruption in the event of a power loss. With softupdates, the filesystem metadata will always be in sync and uncorrupted (barring media failure of course). -gordon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
