these two functions will be used to support all exec() functionality
going into a single library shared by RS and VFS and exec() knowledge
leaving VM.
. third-party mmap: allow certain processes (VFS, RS) to
do mmap() on behalf of another process
. PROCCTL: used to free and clear a process' address space
. make ramdisk buildable without ../etc having pwd.db
. add cat to release bootstrap cmds
. support running dynamically linked executables for
release bootstrap cmds
. import netbsd chroot to help
See UPDATING about upgrading clang for dynamic linking.
. allow executables on ramdisk to be dynamically linked; this means
putting a few required shared libraries and ld.elf_so on the ramdisk.
. this makes the ramdisk (usage) smaller when they are dynamic, but
bigger when they're not.
. also we can safely ditch newroot and call mount directly as that is
all newroot does.
. create proto.common to share a bunch of entries between
small/nonsmall cases
remove some old minix-userland-specific stuff
. /etc/ttytab as a file, and minix-compat function (fftyslot()),
replaced by /etc/ttys and new libc functions
. also remove minix-specific nlist(), cuserid(), fttyslot(), v8 regex
functions and <compat/regex.h>
. and remaining minix-only utilities that use them
. also unused <compat/pwd.h> and <compat/syslog.h> and
redundant <sys/sigcontext.h>
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
With -n -b file, a.out boot images can be used for CD booting;
with the new -n -B file option, plain binary (like bootxx_cd9660)
can be used instead.
Restore working the -h and -f options while there.
And add a new -F option for 2.8MB floppy image.
Register file timestamps
Remember the path tables in the primary descriptor
Put the size of the parent directory in the \1 entry, not own size
Allow the use of -b option without -a
Notes:
* Still missing the man page
* Filenames are still trimmed to 12 characters, because of
8.3 MS-DOS inherited compatibility (ISO9660 level 1);
also note that 7.4 or 9.2 filenames are accepted though
* Final . at end of filenames without extension is still missing
* VMS-compatible ;1 version suffix is still omitted
* Limit of 65,535 directories in path tables is not checked
