      4 # Environment variables without default values:
      5 #   DESTDIR must be set before anything in this file will work.
      6 #   RELEASEDIR is where the tarred up stuff for a snapshot or
      7 #	release will be placed.
      8 #
      9 # Environment variables with default values:
     10 #   LOCALTIME will set the default local time for the system you
     11 #	build; it determines what /etc/localtime is symlink'd to.
     12 #   KERNSRCDIR points to kernel source; it is set by default to ../sys,
     13 #	but can be overridden.
     14 #   KERNOBJDIR is the kernel build directory, it defaults to
     15 #	${KERNSRCDIR}/arch/${MACHINE}/compile, but can be overridden.
     16 #   KERNCONFDIR is where the configuration files for kernels are found;
     17 #	default is ${KERNSRCDIR}/arch/${MACHINE}/conf but can be overridden.
     18 #   MKUPDATE; if not `no', don't do a 'make clean' before kernel compile
     19 #   NO_SENDMAIL is normally undefined; if defined, it will not do a
     20 #	`make distribution' in the sendmail config file source directory.
     21 #
     22 # Targets:
     23 #    distribution: makes a full NetBSD distribution in DESTDIR. If
     24 #	INSTALL_DONE is set, it will not do a `make install.'
     25 #	if DISTRIBUTION_DONE is set, it will not do anything.
     26 #    distrib-dirs: creates an empty NetBSD directory tree in DESTDIR.
     27 #	Called by distribution.
     28 #    snapshot: calls distribution, above, and then tars up the files
     29 #	into a release(7) format in RELEASEDIR/${MACHINE}.
     30 #	Any port-dependent stuff for this target is found in
     31 #	etc.${MACHINE}/Makefile.inc.
     32 #    release: a synonym for `snapshot'

    405 #				are also placed in the binary/kernel
    406 #				area of the release package as
    407 #				netbsd-${kernel}.gz.
    408 #

    410 #				binary/kernel area of the release
    411 #				package as netbsd-${kernel}.gz, but
    412 #				which are not placed into sets. This
    413 #				allows a port to provide e.g. a netbootable
    414 #				installation kernel containing a ramdisk.
    415 #
    416 #	BUILD_KERNELS		Additional kernels to build which are
    417 #				not placed into sets nor into the
    418 #				binary/kernel area of the release
    419 #				package.  These are typically kernels
    420 #				that are built for inclusion only in
    421 #				installation disk/CD-ROM/tape images.
    422 #
    423 #	A port may also specify KERNEL_SUFFIXES, which is an optional list
    424 #	of filename suffixes for kernels to include in the kernel sets and
    425 #	in the binary/kernel area of the release package (e.g. "netbsd" vs.
    426 #	"netbsd.ecoff" and "netbsd.srec").  It is not an error if kernels
