The only way to install a new kernel is to reboot the system. If you're upgrading the software, you are *strongly* encourage to boot the new kernel before upgrading any other software. That way, if it fails it's easy to go back to the old situation. If you upgrade the rest of the system and it fails, you wind up trying to fix things with the old kernel and new userland, which may be arbitrarily difficult. =09<mike -- Mike Meyer <mwm@mired.org>=09=09=09http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more inform= ation.
