# This script does a 'make installworld' using the *old* versions of all
# commands to do the work. It expects that the new kernel has been installed,
# but that the system has not been rebooted (and is thus still running on the
# previous kernel). This is useful when a major incompatible change is made,
# and you want to do an installworld that uses NFS-mounted directories for
# /usr/src and /usr/obj. This script was written for the change to
# 64-bit time_t on FreeBSD/Sparc64, but it is not specific to that.
#
# IMPORTANT: This script does require that you are NOT YET running on
# the new kernel that matches the 'world' that you want to install.
#
# -------+---------+---------+---------+---------+---------+---------+---------+
# This script expects that it will be run from /usr/src, or an
# equivalent (perhaps NFS-mounted) directory.
