# Install new world and kernel built in /usr/src. This should be done in
# single user mode, or at least on a very quiet system. Presumes system
# has been built using update_fbsd
#
# Note that this does not follow the best recommended procedure, which
# involves installing and booting the new kernel before installing the new
# world. The risk is that a broken world will render a system unbootable
# with both new and old kernel. Caveat emptor. See the FreeBSD Handbook and
# /usr/src/UPDATING for more details.

# The latest version of this script and its companion, update_fbsd can be

# My kernel config file and sup files, along with other system config
# files can be found in http://halplant.com:88/server/config/
