The CD now boots directly from the ISO 9660 filesystem instead of using
MBR partitioning with Minix file systems. This saves some space on the
CD and reduces memory requirements by some unknown amount as the root
ramdisk is completely eliminated.
The x86 hard drive image creation is also rewritten in the same
fashion.
The setup is modified to be more NetBSD-like (unpacking sets
tarballs instead of blindly copying the CD contents). Splitting MINIX
into sets is done in another commit due to it being a nightmare to
rebase.
Since MINIX lacks union mounts for now, a bunch of ramdisks are
generated at run-time to make parts of the filesystem writeable for the
CD. This solution isn't ideal, but it's enough for an installation CD.

This patch adds support for Unix98 pseudo terminals, that is,
posix_openpt(3), grantpt(3), unlockpt(3), /dev/ptmx, and /dev/pts/.
The latter is implemented with a new pseudo file system, PTYFS.
In effect, this patch adds secure support for unprivileged pseudo
terminal allocation, allowing programs such as tmux(1) to be used by
non-root users as well. Test77 has been extended with new tests, and
no longer needs to run as root.
The new functionality is optional. To revert to the old behavior,
remove the "ptyfs" entry from /etc/fstab.
Technical nodes:
o The reason for not implementing the NetBSD /dev/ptm approach is that
implementing the corresponding ioctl (TIOCPTMGET) would require
adding a number of extremely hairy exceptions to VFS, including the
PTY driver having to create new file descriptors for its own device
nodes.
o PTYFS is required for Unix98 PTYs in order to avoid that the PTY
driver has to be aware of old-style PTY naming schemes and even has
to call chmod(2) on a disk-backed file system. PTY cannot be its
own PTYFS since a character driver may currently not also be a file
system. However, PTYFS may be subsumed into a DEVFS in the future.
o The Unix98 PTY behavior differs somewhat from NetBSD's, in that
slave nodes are created on ptyfs only upon the first call to
grantpt(3). This approach obviates the need to revoke access as
part of the grantpt(3) call.
o Shutting down PTY may leave slave nodes on PTYFS, but once PTY is
restarted, these leftover slave nodes will be removed before they
create a security risk. Unmounting PTYFS will make existing PTY
slaves permanently unavailable, and absence of PTYFS will block
allocation of new Unix98 PTYs until PTYFS is (re)mounted.

The expected argument name would include the instance number, which
is not only redundant in many cases (FOOETHn_n=arg.., "n" being the
instance number) and conflicted with what netconf(8) does, but some
drivers need to be able to see the arguments for all instances of its
driver type--for example, dp8390 needs to know how many earlier
instances have been configured to use PCI.

- Adding missing fields for PCI device lookup
- Adding the domain (for now set to zero) as part of the slot name
Change-Id: Iebaf3b21f6ab5024738cbc1dea66d5ad3ada175d
- This improves the user messages.
- This update the pkgsrc checkout rules to point to the new repository,
as well as the new work process we are introducing.
- This introduces rules for the MINIX sources, as we don't have the
space anymore to distribute them by default on the official ISO.

changes:
. change reboot() call to netbsd prototype and args
. allows pristine <utmp.h>
. use clean <sys/reboot.h> instead of <minix/reboot.h>
. implement TIOCSCTTY for use by getty so getty can get
controlling terminal from init's child(ren)
. allow NULL envp for exec

BeagleBone Capes add additional hardware to the BeagleBone to
improve functionality.
This patch probes the third i2c bus for capes and loads the
appropriate drivers for each detected cape. Currently only
the 'BeagleBone Weather' cape is supported.

On the BeagleBoard-xM, the RTC is located on the Power Management IC
(PMIC). To keep things consistent, access to the PMIC's RTC is done
through the readclock driver. The readclock driver forwards the request
on to the TPS65950 driver which does the work of manipulating the
registers on the chip.

This program uses the i2c /dev interface to read the
contents of EEPROMs and display it to the user in
HEX and ASCII. It also has a mode that can display
data in label:value pairs. That mode is used for
board detection in the rc script to start the right
i2c drivers for the board.

To use the new SD building script, Linux has to be configured with
loop.max_part=15 on the command line (or set at module load time)
to make the loopback device see the partitions.
This commit removes a lot of differences between the ARM and x86
boot ramdisk and rc scripts. It changes the ARM build from running
from ramdisk to requiring a full filesystem on the SD image and
booting into it.
. ramdisk: remove some arm-only utilities only used for running
from the shell
. remove ARM-only rc.arm, proto.arm.small, ttys and mylogin.sh
boot-time ramdisk files
. change kernel to add "arch" variable so userland knows what
we're running on from sysenv
. make ARM use the regular ramdisk rc file, changed to distinguish
i386-only and ARM-only drivers; requires rootdevname to be set
. change /etc/rc and /usr/etc/rc to start i386-only drivers only on
i386 systems
. change the kernel/arm to have a special case for the memory
driver to load it higher so it can be bigger
. add uEnv.txt, cmdline.txt and a for now highly linux-dependent
SD preparation script arm_sdimage.sh to the git repository in
releasetools/

The rc script manually parses /etc/fstab to mount all file systems.
To do that it needs /bin/sed which does not exist anymore. mount(8)
now supports the -a flag which causes it to mount all file systems
listed in /etc/fstab except for '/'. File systems marked with 'noauto'
are skipped.
- libnetsock - internal implementation of a socket on the lwip
server side. it encapsulates the asynchronous protocol
- lwip server - uses libnetsock to work with the asynchronous
protocol
. rc script and service know to look in /usr/pkg/.. for
extra binaries and conf files
. service split into parsing config and doing RS request
so that a new utility (printconfig) can just print the
config in machine-parseable format for netconf integration
. converted all base system eth drivers/netconf
. 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
. add bsd-style MLINKS to minix man set, restoring aliases
(e.g. man add64 -> int64)
. update daily cron script to run makewhatis and restore makewhatis
in man Makefile (makedb), restores functionality of man -k
. netbsd imports of man, mdocml, makewhatis, libutil, apropos
. update man.conf with manpage locations, restoring man [-s] <section>
. throws out some obsolete manpages
. 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
. use bmake for pkgsrc instead, reads mk.conf from /usr/pkg/etc/mk.conf
. tracking bmake from pkgsrc eases tracking pkgsrc
. further disentangles pkgsrc from base system, reducing maintenance
burden of pkgsrc
