   3 # KERNSRCDIR    Is the location of the top of the kernel src.
   4 #               It defaults to `${NETBSDSRCDIR}/sys'.
   5 #
   6 # KERNARCHDIR   Is the location of the machine dependent kernel sources.
   7 #               It defaults to `arch/${MACHINE}', but may be overridden
   8 #               in case ${MACHINE} is not correct.
   9 #
  10 # KERNCONFDIRDEFAULT    Is the default for ${KERNCONFDIR}.
  11 #               It defaults to `${KERNSRCDIR}/${KERNARCHDIR}/conf'.
  12 #
  13 # KERNCONFDIR   Is where the configuration files for kernels are found.
  14 #               Users can set this to have build.sh find kernel
  15 #               configurations in another directory.
  16 #               It defaults to `${KERNCONFDIRDEFAULT}'.
  17 #
  18 # KERNOBJDIR    Is the kernel build directory.  The kernel GENERIC for
  19 #               instance will be compiled in ${KERNOBJDIR}/GENERIC.
  20 #               The default is the .OBJDIR of
  21 #               `${KERNSRCDIR}/${KERNARCHDIR}/compile'.
