	N/A

>Description:

	The kernel makefile unconditionally sets kern.bootfile to point to
	the backup version of the old /kernel.  If /kernel isn't what you
	booted, this fails to fix up things like ps.

>How-To-Repeat:

	>> boot /kernel.stable
	# cd /sys/compile/MYKERNEL
	# make install
	# ps

>Fix:
	
	Perhaps the following:

	if [ `sysctl -n kern.bootfile` = /kernel ]; then
		sysctl -w kern.bootfile=/kernel.old
	fi
