If the new kernel doesn't boot, you've still got the previous one in /kernel.old, so you can just boot from that one and carry on without having trashed any part of your system. If installworld somehow manages to make your system unbootable, you have a few options: - boot single-user and try to fix things with the tools in /stand (or /rescue on 5.x) - boot CD #2 and try to fix things with the tools in the live filesystem - restore from backups (you do have backups, right?) Personally, I've made plenty of unbootable kernels, and a few worlds that behaved strangely in places, but never an unusable system (fingers crossed :-) Scott
