Ooooooooooh, those are the scary ones. Two excellent things can help with that: A proper RAC setup, or Copy the debian boot scheme, where is a kernel won't boot, it panics and times out after 30 seconds. Grub then automagically boots the previous working kernel. Just don't do what I did earlier: sit in Joburg and configure the firewall on a Xen host in deepest darkest Africa where there's no tarred roads to get to it. Check the iptables config three times, plus get your colleagues to look it over as well. We all signed off on it. Guess what? Yup, you got it. We all missed something and now we are locked out. Remember, it's in deepest darkest Africa. <sigh> -- Alan McKinnnon alan.mckin...@gmail.com
