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
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.
. detect both formats in /etc/rc
. generate new format in setup
. obsoletes /etc/fstab.local: everything can go in /etc/fstab
. put shutdown/reboot/halt and a copy of /usr/adm/wtmp
(/etc/wtmp) on root FS so that we can do shutdown checks before
mounting /usr
. new fstab format makes getfsent() and friends work
. speeds up mkdep (i.e. world builds) significantly
. have to keep minix /bin/sed for a while because previous
usr/etc/rc depends on it
. force mkdep to use /usr/bin/sed for speedup
. Feature to do a 'release' into a permanent
and usable FS hierarchy, usable with chroot
. Just like the temporary staging hierarchy really
. Useful to checking out and building the latest
version of minix from a host minix; to
(1) make an uptodate minix jail, and
(2) make a sterile, reproducible jail environment, and
(3) use as disposable environment in which moving /usr/pkg
is ok
(i.e. pkgsrc bulk builds)
Add two makefiles to manage compiling packages with NetBSD libc.
* minix.libc.mk contains the proper CFLAGS/LDFLAGS
* pkgsrchooks.mk contains the logic for setting the flags.
* update bmake
Several pkg-config files were added to help pkgsrc learn about
the c, minlib, and compat_minix libraries.
and minor fixes:
. add ack/clean target to lib, 'unify' clean target
. add includes as library dependency
. mk: exclude warning options clang doesn't have in non-gcc
. set -e in lib/*.sh build files
. clang compile error circumvention (disable NOASSERTS for release builds)
. when switching from the base pkg_install to the pkgin pkg_install,
the version number changed, causing a compatability problem if the
old base system binary was inadvertently left behind.
. this change checks for that situation by specifically invoking
the pkgin instance of pkg_install and telling the user to install
it if it doesn't exist.
pkgsrc binary packages.
rationale:
. pkg_install (which is the pkg_* tools) is entangled with pkgsrc,
not with minix, so tracking it from pkgsrc (easier than with
base system) makes more sense
. simplifies upstreaming minix specific changes for pkg_* tools
. reduce pkgsrc-in-basesystem maintenance burden
. update release.sh's notion of where packages are
. update release.sh's notion of how many files are on root
as -xdev won't work anymore to separate /usr from /
- A staging directory is always used to avoid oversized images;
- As a consequence, the zero-filling is removed so no more "out of
space" errors should be printed to the console;
- The root and usr partition sizes are computed so less space should be
wasted (the root partition gets extra 1MB zones and 64 inodes for
run-time though and hardlinks/holes make the used space slightly less
than expected); USRMB (and the new ROOTMB) are now used to enforce
a minimum size rather than set the size;
- TMPDISK1-3 are renamed to more meaningful names (and TMPDISK2 is
dropped because a separate tmp directory is no longer needed);
- The ramdisks are truncated at the end to save memory (not sure
whether it is actually released though).
boot is a normal binary with a.out again. use 'cdbootblock,' a CDBOOT
variant of bootblock, both from bootblock.s, as the first boot image
that then loads boot, exactly like the bootblock loads boot when booting
from harddisk. the sector numbers (2048 byte iso sectors) are patched in
by writeisofs, like installboot does for bootblock. bootblock unchanged.
