Yes, first off I've been lead to believe (through comments on the list, and my own experience) that you cannot use /stand/sysinstall from one release to install another. What you need to do, is to boot the system (with the floppies or a CD) with the release you want to install, then select upgrade. And, if your system was hacked, I believe it would be a good idea to start from scratch. Don't upgrade, repartition and then reinstall. It's impossible to know everything that was gotten into or changed. The only way to make absolutely sure that it's clean is to start from scratch. -Mark To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
