I would not recommend people try this unless the only alternative is a reinstall. If something goes wrong and you can't figure it out, you may have to do the reinstall anyway. I just wanted to reiterate that to make sure that everybody understands the situation... The difficulty is working around the catch-22 situation where you need a new kernel first so you can install world, and you need a new world first before you can boot the new kernel. Cheating and using the swap partition for a temporary world is one way around it. It might even be necessary to do a new buildworld inside the temporary world if you can't reinstall the previous one. Some creativity will be needed. -- Peter Wemm - peter@wemm.org; peter@FreeBSD.org; peter@yahoo-inc.com "All of this is for nothing if we don't go to the stars" - JMS/B5
