1. Remove all the special handling of variables (-d -p -P -s -S) that
were dealing with DBG (-d) LDSTATIC/NOPIE (-p), and the rest with
disabling/enabling sanitizers.
2. Use emalloc/estrdup for all the allocators instead of only some cases.
3. Add -V varspec which passes variables on the command line (as DBG
and LDSTATIC used to be passed before) instead of appending them
to the on-the-fly Makefile using -v varspec.
4. Change the distrib and rescue Makefiles to use -V instead of the removed
flags.

The motivation of this is to make variable handling consistent, less magical,
and remove the need for changing crunchgen each time we want to add disabling
an option by default.

(as proposed in tech-toolchain)

branches: 1.68.48;
${NETBSDSRCDIR}/distrib/common/protocols => ${DISTRIBDIR}/common/protocols
${NETBSDSRCDIR}/distrib/common/services => ${DISTRIBDIR}/common/services

Use the cutdown distrib/common/services and distrib/common/protocols
rather than the full fat etc versions

Add ${IMAGE}.gz to dependency list of release:: target as well as the one
in src/distrib/common/Makefile.image so that ${MAKESUMS} will be invoked
after the target image is installed into the releasedir, not before,
even if make -jN is specified.

XXX some ports do ${MAKESUMS} for installation/miniroot files
XXX in etc/etc.${MACHINE}/Makefile.inc later again.

Change remaining instances of ${RELEASEDIR}/${MACHINES} to
${RELEASEDIR}/${RELEASEMACHINEDIR}

branches: 1.64.12; 1.64.16;
Since /etc/services has gotten rather large, use a minimal one for install
kernels. (mount_nfs is notably the only binary that doesn't gracefully deal
with the lack of an /etc/services file, it appears.)

branches: 1.63.16; 1.63.20;
Install release files under "${RELEASEDIR}/${MACHINE}/..." instead of
"${RELEASEDIR}/...".

${RELEASEDIR} is never cleaned , and ${RELEASEDIR}/${MACHINE} is only
cleaned if UPDATE is not defined.

enable (default) libhack for all miniroots.
for atari, also add gethost.o (as before)

Use release:: instead of release: when multiple release targets may exist

yet another distrib overhaul:
- move guts of distrib/Makefile.inc to distrib/common/Makefile.distrib
(fixes problem caused by implicit include of ../Makefile.inc in certain
submake conditions triggered by makefiles not yet in tree)
- removed mkdir of ${RELEASEDIR}/*; rely upon "snap_pre" target of
etc/Makefile to create all the release directories
- renamed RELINSTALL to RELEASE_INSTALL
- renamed FLOPPYINSTDIR to FLOPPY_RELEASEDIR
- renamed MDSETDIR to MDSET_RELEASEDIR
- removed ITARGET
- move release target from top level to appropriate subdirectory
- ensure release target has correct depends
- replace miniroot's IMAGE_MD_POST with common/Makefile.image IMAGEPOSTBUILD
- Makefile.image: add realall: ${IMAGE}

replace _SRC_TOP_ with NETBSDSRCDIR, since the latter is the "public" version

Make sure DBG setting is passed to crunch Makefile to get proper
compile-time options.

- replace image_md_post: target with IMAGE_MD_POST variable, and use
that after building ${IMAGE}
- use ${IMAGEBUILT} to ensure that IMAGE_MD_POST is only run if IMAGE changes

remove MAKESUMS (provided by ../Makefile.inc). minor tweaks

tweak how distrib/Makefile.inc is pulled in. use realall: instead of all:

Set CKSUM in makesums' environment.

add empty image_md_post rule so ports that don't provide one won't barf

If we're going to use DISTRIB(REV|VER) in generated files, have those files
depend upon osrelease.sh. Issue raised by Havard Eidnes.

need to pass DISTRIBREV and DISTRIBVER to parselist as well

parselist.awk
- improve comments
- provide a general purpose variable replacement; replace contents of ${FOO}
with ENVIRON["FOO"].
- deprecate @MACHINE@ and @MACHINE_ARCH@ in favour of using ${MACHINE}
and ${MACHINE_ARCH} instead
- add errx() function; like err(), but doesn't print the line number
- invoke this script with various variables defined via PARSELISTENV

*/Makefile*
- use PARSELISTENV instead of POPULATEENV, and add variables like DESTDIR
- other minor tweaks

*/list*
- replace @MACHINE@ with ${MACHINE}

Commit work-in-progess rototill of distrib/miniroot and associated machine
dependent files:

- Use infrastructure from distrib/common to build file system images with
crunchgen-ed programs from a list file.

- Non root ("UNPRIVED") builds from a read-only source tree are possible,
as makefs(8) replaces vnconfig(8)/vnd use, devices are generated using
common/makedev2spec.awk, etc.

- Cross builds should be possible, except that some ports need cross-compile
host tool versions of installboot and any appropriate host disk labelling
tools.
XXX: pmax, sparc and vax need fixing for this!

- This code has NOT YET BEEN TESTED on most of the ports.
It should work, but it is extremely likely that the file system
parameters may need tweaking to get things to fit.
See MAKEFS_FLAGS in sparc/miniroot/Makefile.inc for an example.
If assistance is required, please ask!

Use the building machine's raw partition instead of fixed "c" to allow
cross-building.

remove REV in favour of DISTRIBREV (from ../Makefile.inc)

don't set the owner or group when installing into $RELEASEDIR

Test DESTDIR and RELEASEDIR for non-emptyness as well as existence, sigh..

Remove instbin.cache from dependency lists, since crunchgen is now run
unconditionally.
Avoid running the crunchgen command multiple times for each dependent
target by marking only one target (instbin.mk) for unconditional re-make.

use 'vnd0' instead of 'vnd0c', when unconfigure device.

Just use vnd0 when vnconfig'ing and then use the char/raw device when newfs'ing
and mounting

Use the block device when invoking "vndconfig" because the character
device isn't accepted any longer.

use raw device name for vnconfig.

Add MTREE?= to add Makefiles and use when running mtree

Use symbol MTREECONF instead of MTREE to refer configuration file
to avoid conflicts. Pointed out by chs@netbsd.org.

Make sure crunchgen remakes the makefile everytime and it doesn't use it's
cache since other Makefiles could change source files too easily.

Change all ocurrences of "crunchgen" to ${CRUNCHGEN}

Use
${MAKE}
instead of
make

Backout previous commit. It shouldn;t have happend.

Pull up revision 1.16 (requested by leo, approved by thorpej).
Log:
Use x_ed and x_route to save space on the miniroot.

branches: 1.32.4;
Updagte the VAX bits so they actually work. Use the common method of building
miniroots. Fix the ramdisk bits. Use the INSTALL kernel. This stuff has
really suffered from bitrot.

Added missing .gz to makesums arg

use bsd.kernobj.mk to tell us KERNOBJDIR for compiled kernels.

Use top-level Makefile.inc to set BSDSRCDIR
use bsd.kernobj.mk to set KERNOBJDIR and pass this to runlist.sh

Fix path to `makesums'

Use relative path to osrelease.sh

Bump image size by 1MB.

Make sure the miniroot distribution directory exists.
Compute the checksums.

Remove version number from boot image files.

Add `release:' targets.

branches: 1.22.2;
s/makeing/making/

Sync with the recent crunchgen changes.
- Remove *.cro files and not the obsoleted *.lo files.

From Bill Studenmund commit message:
> 3) Generate .cro files rather than .lo files. .lo now is used for "local
> objects" - obj's for the host machine not the target machine.

use an async mount for building the miniroot filesystem

branches: 1.19.2;
Add hook for running extraneous commands before newfs.

distclean is a synonym for cleandir

We don't need to manually flush the buffer cache after ``vnconfig -u''
anymore.

Add a VND_GEOM variable for optionally specifying a geometry
to vnconfig(8).

More changes, while working on Amiga generic miniroot stuff:
- added method BOOTINSTALL, for an architecture to optionally install a
bootblock in the miniroot (this works for Amiga)
- added Amiga keymap directories
- removed the subdir selection from mount_local_disk() and mount_nfs(), and
the remains from mount_cdrom(), as all are handled now by the subdir
navigator in mount_from_installed_fs()

Make DISKTYPE optional; default to vnd's builtin geometry.
Make `vnd0c' the default vnd device (instead of `vnd0a').

Update for changes to vnconfig(8).

Don't hardcode in the current release information; generate it
automatically on the fly, by using
`sh ${BSDSRCDIR}/sys/conf/osrelease.sh -s`

Bump the REV to 12D to get in sync with param.h and newvers.sh.
This REALLY needs to be in ONE file and not in 11 files.

Include <bsd.own.mk> for <bsd.obj.mk>. Bump rev to 12B (HI PERRY! :-)

Merge the netbsd-1-2 branch back into the mainline.

Check for $DESTDIR being set. This prevents you from accidently ending up
with a miniroot that contains your local passwd files.

We're 1.2A, I promise.

* Edit VERSION into install.sub while copying instead of using a
VERSION file.
* Set the EDITOR variable in install.sub, so it will be set in both
upgrade & install.
* Make the checks on the presence of installation sets on the local
disks on upgrade more precise.
* Remove more&less from the list of standard binaries (I need more space!)
* When building an fstab from the users' fstab, drop lines starting with
a '#' and lines with an fstype that is not supported on the miniroot.

Remove leftover from atari (floppybt -> miniroot)

Sync atari miniroot & mi-miniroot

Include machine-specific makefile so the default values of various
things can be overridden.

branches: 1.2.4;
update clean target

Attempt at a MI miniroot build environment, converted from hp300 version.
Note:
- `list' was more-or-less arbitrarily split into MD & MI parts.
- the `crunch' configuration file is generated from `list's
with the `makeconf' awk-script.
- Makefile assumes there's a `../<arch>/miniroot' directory with
MI configuration files.
