Suddenly we have a filesystem that writes slower than Solaris and that slows down the entire box. Also, as a desktop OS many people noticed that their FreeBSD boxes were writing much slower than even the Windows NT boxes. It was really painful. Finally, the people who really need the sort of protection that sync writes gives are the kind who will know to turn off the write cache. A sysinstall prompt would be nice though. An even nicer option would be a little menu on the diskLabel part of the install that asks what options you want to enable on the filesystem when you create it (softupdates, etc...). -- \ |_ _|__ __|_ \ __| Jason Andresen jandrese@mitre.org |\/ | | | / _| Network and Distributed Systems Engineer _| _|___| _| _|_\___| Office: 703-883-7755 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
