If things fail, you just reboot, and it goes back to the old kernel. If things work, then it's a simple rename of the kernel directory: cd /boot mv kernel kernel.old mv kernel.new kernel reboot KODIR and nextboot are very handy ... especially for remote upgrades. -- Freddie fjwcash_at_gmail.comReceived on Tue Feb 24 2009 - 20:20:43 UTC
