(I must have forgotten to commit this at the same time).
sysinst still runs in 16MB (and hasn't run in 8MB for a while).
The extra space costs almost nothing on the compressed 'floppies', but
gives more working room for the install system (eg sysinst can coredump
without filling /).
<sys/bootblock.h>:
* Added definitions for the Master Boot Record (MBR) used by
a variety of systems (primarily i386), including the format
of the BIOS Parameter Block (BPB).
This information was cribbed from a variety of sources
including <sys/disklabel_mbr.h> which this is a superset of.
As part of this, some data structure elements and #defines
were renamed to be more "namespace friendly" and consistent
with other bootblocks and MBR documentation.
Update all uses of the old names to the new names.
<sys/disklabel_mbr.h>:
* Deprecated in favor of <sys/bootblock.h> (the latter is more
"host tool" friendly).
amd64 & i386:
* Renamed /usr/mdec/bootxx_dosfs to /usr/mdec/bootxx_msdos, to
be consistent with the naming convention of the msdosfs tools.
* Removed /usr/mdec/bootxx_ufs, as it's equivalent to bootxx_ffsv1
and it's confusing to have two functionally equivalent bootblocks,
especially given that "ufs" has multiple meanings (it could be
a synonym for "ffs", or the group of ffs/lfs/ext2fs file systems).
* Rework pbr.S (the first sector of bootxx_*):
+ Ensure that BPB (bytes 11..89) and the partition table
(bytes 446..509) do not contain code.
+ Add support for booting from FAT partitions if BOOT_FROM_FAT
is defined. (Only set for bootxx_msdos).
+ Remove "dummy" partition 3; if people want to installboot(8)
these to the start of the disk they can use fdisk(8) to
create a real MBR partition table...
+ Compile with TERSE_ERROR so it fits because of the above.
Whilst this is less user friendly, I feel it's important
to have a valid partition table and BPB in the MBR/PBR.
* Renamed /usr/mdec/biosboot to /usr/mdec/boot, to be consistent
with other platforms.
* Enable SUPPORT_DOSFS in /usr/mdec/boot (stage2), so that
we can boot off FAT partitions.
* Crank version of /usr/mdec/boot to 3.1, and fix some of the other
entries in the version file.
installboot(8) (i386):
* Read the existing MBR of the filesystem and retain the BIOS
Parameter Block (BPB) in bytes 11..89 and the MBR partition
table in bytes 446..509. (Previously installboot(8) would
trash those two sections of the MBR.)
mbrlabel(8):
* Use sys/lib/libkern/xlat_mbr_fstype.c instead of homegrown code
to map the MBR partition type to the NetBSD disklabel type.
Test built "make release" for i386, and new bootblocks verified to work
(even off FAT!).
Update lists for ramdisks to include the required files.
NB /usr/sbin/installboot is not used by sysinst and is only in ramdisk-big.
Increase the sizes of the ramdisks, there is plenty of space in all the
boot floppies except rescue-tiny (2k) and boot-tiny (32k).
in sys/arch/i386/conf/INSTALL_TINY
- bump IMAGESIZE from 1460k to 1480k
in distrib/i386/floppies/ramdisk-tiny/Makefile
so that "build.sh release" works again.

version of bootlap[12].fs.
This is suitable for using as a boot file for an El Torito CD-ROM image
to be used to boot laptops, as it has the INSTALL_LAPTOP kernel
(instead of the INSTALL kernel that bootbig.fs has).
There's two variables added to Makefile.crunch:
SMALLPROG If 1, add SMALLPROG=1 to CRUNCHENV. [default: 1]
This can be used by various Makefiles to
determine if a `small' version of the program
is required.
SMALLPROG_INET6 If 1 and SMALLPROG == 1, add SMALLPROG_INET6=1
to CRUNCHENV. [default: 0]
This can be used by various Makefiles to
determine if the `small' version has INET6
support enabled.
Only enable SMALLPROG_INET6 for programs on the ramdisks that have INET6 in
the appropriate kernel, and cleanup INET6 setting.
(Note: this means that sysinst won't get INET6 support if the kernel
it's running on doesn't have it).
This change saves a fair bit of space on various install images
(including i386 ramdisk-{ps2,small,tiny}) that didn't have INET6 in
the kernel but were unconditionally getting INET6 support in their tools.
floppy (and there's not the same RAM contraints that *-tiny has),
fold rescue-small into boot-small and deprecate the former.
The "all in one" boot-small is only 100KB larger on the second floppy.
of a single 1.2MB floppy; cranky FLOPPYMAX to use two floppies.
the kernel and the contents of the ramdiskbin have both grown...
(We should just merge the install & rescue functionality of the -small
floppies into one two x 1.2MB floppy set, since -small is for older
machines with 1.2MB floppy drives, versus those with extremely small
RAM constraints)
../../common/Makefile.mdset supports building multiple copies of the
same kernel (as long as they're to separate filenames).
Now there's no need to set FLOPPYKERNDIR, as it now defaults to instkernel.
- build (mdset/nm/strip) into ${filename} as one rule, and move ${filename}.gz
into separate rule
- rename MDSET.${filename}.nosymbols -> MDSET_NOSYMBOLS.${filename}
- rename MDSET.${filename}.post -> MDSET_POST.${filename}, and don't do
suffix handling here
- rework suffix handling:
- rename MDSET.${filename}.suffixes -> MDSET_SUFFIXES.${filename},
and change from list of suffixes to list of "suffix cmdtobuildsuffix",
where cmdtobuildsuffix is the name of the variable containing the
command to build ${filename}.${suffix} (available as "${.TARGET}").
- for each ${filename}.${suffix}, depend upon ${filename} and use
${cmdtobuildsuffix} to create the former.
- add separate ${filename}.${suffix}.gz rule
- mipsco & pmax: rename "install.gz" to "netbsd-INSTALL.gz", for
consistency and so the target to build the mdset kernel doesn't get
confused with general "install" target
rather than the previous ".fs").
- add support for (optional) FLOPPYSUFFIX in Makefile.tarfloppy, and
use appropriately
- remove (now unnecessary) custom release targets in alpha/instkernel/*
- 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: ${IMAGE}
single and multi-volume floppies in better fashion that the crufty
shell commands in the various Makefiles.
- Move fdset* -> bootfloppy*, as that's more consistent
replace
TARGETS = KERNEL IMAGE [...]
with
MDTARGETS = KERNEL IMAGE FILENAME [...]
If FILENAME is "-", use "netbsd.${KERNEL}" as the target filename
The rest:
Update for new MDTARGETS syntax. In some cases, the kernel
name from the "old" method will be used to override the default.
