	I see nothing which seems likely to be relevant; the system is
	3.0 straight out of the box.
Architecture: i386
Machine: i386
>Description:, when run naively in an attempt to build a new kernel
	on a fresh system, fails.  Since it is the documented way to
	build kernels now, I believe that it should deal with creating
	whatever is necessary to work when run without special options
	out of the box, which is why I've classed this as sw-bug.  If
	this really is the desired behaviour, this should be
	reclassified as a doc-bug; at the very least the kernel=
	operation in BUILDING should mention that it won't work unless
	/usr/obj is manually created first, and it should be emphasized
	that "tools" is not optional (BUILDING implies that it is, when
	the installed tools match the source).
	Install a new system.  Install the sources from the source .tgz
	files.  Then, as root,

	# cd /usr/src
	# sh kernel=GENERIC rebuilds make...
	cc  -O -o nbmake *.o  
	BSDOBJDIR /usr/obj does not exist, bailing...
	*** Failed target:  obj
	*** Failed command: cd /usr/src/tools; ...very long line...
	*** Error code 1
	nbmake: stopped in /usr/src/tools
	ERROR: Failed to make obj in tools
	# mkdir /usr/obj
	# sh kernel=GENERIC rebuilds make again(!)...

	ERROR: nbconfig failed for GENERIC
	Dunno.  As a workaround, I created /usr/obj manually and told to do "tools" (which, in passing, is extremely
	wasteful, as it builds a lot of junk - slow-to-buid junk - that
	is totally unnecessary for building a kernel).
