from a 32-bit value to a 64-bit value. This commit does not actually change anything. It merely provides instructions, scripts, and a safety measure in Makefile.inc1 for people who want to make the change. The real change to 64-bit time_t's on sparc64 is scheduled to happen on March 10th, assuming that so major problems are found between now and then by early-adopters. Reviewed by: freebsd-sparc64

# 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.
