. build writeisofs as a native tool too for it
. also mkfs.mfs: make missing file in proto nonlethal
. make setup script a little more self-sufficient
. hdboot: use INSTALL_FILE instead of INSTALL so that the
results get added to the METALOG

A script that creates a HD image ready to be booted by an x86
emulator, ready to work in a crossbuild environment.
It's really just for qemu/kvm as there's no boot code in
the MBR and no bootloader installed so we rely on the in-kvm
multiboot implementation for now. This is very convenient for
passing args too.
To minimize reliance on external tools, we use the Minix
'partition' utility to write the partition table of the HD
image, which therefore has to be compiled natively.
. new script releasetools/x86_hdimage.sh
. natively compile minix 'partition' utility
. make <machine/partition.h> 64-bit safe for it

- Enable installing binutils from the base system.
- Import texinfo which is required for the binutils tools
to be compiled.
- Also adapted the fetch rules to correctly generate the
gitignore files for gcc, and allow the case of multiple
modules in the same directory, as found in gnu/dist.
Warning: This patch has an entry in docs/UPDATING

upgrade to NetBSD CVS release from 2012/10/17 12:00:00 UTC
Makefiles updates to imporve portability
Made sure to be consistent in the usage of braces/parenthesis at
least on a per file basis. For variables, it is recommended to
continue to use braces.
The tested targets are the followgin ones:
* tools
* distribution
* sets
* release
The remaining NetBSD targets have not been disabled nor tested
*at all*. Try them at your own risk, they may reboot the earth.
For all compliant Makefiles, objects and generated files are put in
MAKEOBJDIR, which means you can now keep objects between two branch
switching. Same for DESTDIR, please refer to build.sh options.
Regarding new or modifications of Makefiles a few things:
* Read share/mk/bsd.README
* If you add a subdirectory, add a Makefile in it, and have it called
by the parent through the SUBDIR variable.
* Do not add arbitrary inclusion which crosses to another branch of
the hierarchy; If you can't do without it, put a comment on why.
If possible, do not use inclusion at all.
* Use as much as possible the infrastructure, it is here to make
life easier, do not fight it.
Sets and package are now used to track files.
We have one set called "minix", composed of one package called "minix-sys"
This decreases external dependencies for crosscompilation. Note that
these libraries are not built nor used by Minix itself.
Furthermore, the shell scripts that download the tarballs for these
libraries, gcc, binutils, and gmake now also support curl in addition
to wget.
This commit finalizes support for cross compilation. The tools
directory are all links to the actual tools and are built on the
host system to build Minix. build.sh is the work horse that takes
care of all environment settings. It's slightly adjusted for Minix.
The /usr/src/Makefile has additional targets needed for cross
compilation.
. Some Makefile fixes to automatically differentiate between a normal
compilation and cross-compilation. Also, build compressed images.
. Harmonize ramdisk rc scripts for normal use case and ext2 ramdisk.
. ext2_ramdisk filesystem prototype fixes.
There is important information about booting non-ack images in
docs/UPDATING. ack/aout-format images can't be built any more, and
booting clang/ELF-format ones is a little different. Updating to the
new boot monitor is recommended.
Changes in this commit:
. drop boot monitor -> allowing dropping ack support
. facility to copy ELF boot files to /boot so that old boot monitor
can still boot fairly easily, see UPDATING
. no more ack-format libraries -> single-case libraries
. some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases
. drop several ack toolchain commands, but not all support
commands (e.g. aal is gone but acksize is not yet).
. a few libc files moved to netbsd libc dir
. new /bin/date as minix date used code in libc/
. test compile fix
. harmonize includes
. /usr/lib is no longer special: without ack, /usr/lib plays no
kind of special bootstrapping role any more and bootstrapping
is done exclusively through packages, so releases depend even
less on the state of the machine making them now.
. rename nbsd_lib* to lib*
. reduce mtree
Kernels and system services are stored in a single directory in the
/boot/minix/ and rotated like /boot/images. /boot/minix_latest slink
is created automatically.
System serives are prefixed by "modNN_" to allow to easily load them
using "mod*" pattern.
Also following functionality was added:
- Add install_master to the installboot from NetBSD.
- Check if enough space for bootxx.
Old installboot was renamed to installboot_minix.
. if the build target is invoked again for the install target, the
stack sizes aren't set properly. A workaround is to only build
and not install the servers. (Installing them doesn't really make
sense anyway.)
3 sets of libraries are built now:
. ack: all libraries that ack can compile (/usr/lib/i386/)
. clang+elf: all libraries with minix headers (/usr/lib/)
. clang+elf: all libraries with netbsd headers (/usr/netbsd/)
Once everything can be compiled with netbsd libraries and headers, the
/usr/netbsd hierarchy will be obsolete and its libraries compiled with
netbsd headers will be installed in /usr/lib, and its headers
in /usr/include. (i.e. minix libc and current minix headers set
will be gone.)
To use the NetBSD libc system (libraries + headers) before
it is the default libc, see:
http://wiki.minix3.org/en/DevelopersGuide/UsingNetBSDCode
This wiki page also documents the maintenance of the patch
files of minix-specific changes to imported NetBSD code.
