In etc/Makefile, there is a description of the variables
KERNEL_SETS, EXTRA_KERNELS, BUILD_KERNELS.
The etc/etc.i386/Makefile has

BUILD_KERNELS=          INSTALL INSTALL_SMALL INSTALL_TINY \
                        INSTALL_LAPTOP INSTALL_PS2  

and the definition is:
#       BUILD_KERNELS           Additional kernels to build which are
#                               not placed into sets nor into the
#                               binary/kernel area of the release
#                               package.  These are typically kernels
#                               that are built for inclusion only in
#                               installation disk/CD-ROM/tape images.

yet they appear in binary/kernel along with RESCUE_SMALL, RESCUE_TINY which
aren't mentioned in etc.i386/Makefile at all. I would have expected
INSTALL* and RESCUE* to be added to EXTRA_KERNELS for that to happen.
How can this be?
