try to quit or stop the program right at the moment after the it
sends a TSTP to init, move the kill(1, TSTP) to right after we
block most signals, instead of doing it just before.
2) To add TSTP to the signals we ignore. Once we start halting, it
really is not safe to try to stop at all. You can't change your
mind halfway through -- init will already be stopped and a TERM
will have been sent to everything on the system within
milliseconds of starting.

o ffs verify_method,
o multiple keygen methods that are xor'ed together

This commit is mostly a forward compatibility patch that can be pulled
up in to the 1.6 branch.
From Kirk Mckusick in FreeBSD (setup.c rev. 1.30). Original commit message:
========
When checking the alternate superblock, we used to copy any fields
that might have changed, then did a byte-by-byte comparison with
the alternate. If any unused fields got used, they had to be added
to the exception list. Such changes caused too many false alarms.
So, I have changed the comparison algorithm to compare a selected
set of fields that are not expected to change. This new algorithm
causes far fewer false hits and still does a good job of detecting
problems when they have really occurred. In particular, this change
should ease the transition to kernels supporting UFS2 which make
some significant changes to the superblock.

I didn't have time to clean it up completely before my legal status
w.r.t. open source projects goes into limbo for a while. Other
developers are encouraged to play with the tool and get it into
release-worthy shape.
TODO list (see TODO file)
* verify it builds on -current, put it into release lists/etc. and src/sbin/Makefile
(built & tested on 1.6.1)
* make it ask questions before doing any work (confirm)
* create regression test suite (see discussions on tech-kern and
developers) and fix any bugs
* verify conversion to ANSI C didn't break anything
* port to UFS2
(there are still some details to work out) but expect that to go
away soon. To support these basic changes (creation of lfs_putpages,
lfs_gop_write, mods to lfs_balloc) several other changes were made, to
wit:
* Create a writer daemon kernel thread whose purpose is to handle page
writes for the pagedaemon, but which also takes over some of the
functions of lfs_check(). This thread is started the first time an
LFS is mounted.
* Add a "flags" parameter to GOP_SIZE. Current values are
GOP_SIZE_READ, meaning that the call should return the size of the
in-core version of the file, and GOP_SIZE_WRITE, meaning that it
should return the on-disk size. One of GOP_SIZE_READ or
GOP_SIZE_WRITE must be specified.
* Instead of using malloc(...M_WAITOK) for everything, reserve enough
resources to get by and use malloc(...M_NOWAIT), using the reserves if
necessary. Use the pool subsystem for structures small enough that
this is feasible. This also obsoletes LFS_THROTTLE.
And a few that are not strictly necessary:
* Moves the LFS inode extensions off onto a separately allocated
structure; getting closer to LFS as an LKM. "Welcome to 1.6O."
* Unified GOP_ALLOC between FFS and LFS.
* Update LFS copyright headers to correct values.
* Actually cast to unsigned in lfs_shellsort, like the comment says.
* Keep track of which segments were empty before the previous
checkpoint; any segments that pass two checkpoints both dirty and
empty can be summarily cleaned. Do this. Right now lfs_segclean
still works, but this should be turned into an effectless
compatibility syscall.

As a side-effect, add PFIL_HOOKS processing to if_bridge.

for forking the traditional UNIX init(8) and it does the Mach port naming
service. We need mach_init for the naming service, but unfortunately, it
will only act as such if its PID is 1. We introduce a sysctl
(emul.darwin.init_pid) to fool a given process into thinking its PID is 1.
That way we can get mach_init into behaving as the name server.
Typical use:
/sbin/sysctl -w emul.darwin.init_pid=$$ ; exec /emul/darwin/sbin/mach_init
These are of use to userland code which previously depended on the
hard-coded values of LABELSECTOR and LABELOFFSET to figure out the
location of the disklabel for a particular platform.
With the introduction of umbrella ports such as evbarm, evbmips, etc,
the location of the disklabel may vary between kernels for the same
MACHINE. This sysctl will allow userland programs to remain independent
of the particular flavour of MACHINE in such cases.
this one had all the infrastructure of fork/exec/wait, like the
others, but called system instead of exec creating an extra PID
and associated memory usage during the edit.
that can be used to block a process after fork(2) or exec(2) calls. The
new process is created in the SSTOP state and is never scheduled for running.
This feature is designed so that it is esay to attach the process using gdb

to reprompt for the passphrase if the key does not meet certain
criteria. The currently implemented methods are ``none'' and
``disklabel''. The first behaves in the original fashion, the
second will scan for a disklabel on the cgd after configuration
and if it does not find a disklabel then it will reprompt for the
password and reconfigure the disk.

Now fdisk -l shows the familiar 169 for NetBSD, 165 for FreeBSD or

Files in subdirectories of directories that have the nodump flag set
are sometimes incorrectly being dumped.
The problem arises because the subdirectory only gets its entry
cleared from usedinomap if it is also present in dumpinomap, and it is
the absence of a directory in usedinomap that internally indicates
that the directory is under the effects of UF_NODUMP (either directly
or inherited).

-dynamic-linker=/libexec/ld.elf_so) if the BINDIR of the program being
built is /bin or /sbin.
The reason we do this is because now all programs *except* those in
/bin and /sbin (i.e. the "special cases") match the default the compiler
uses, which is what is used for things in e.g. xsrc, pkgsrc, and other
random 3rd party programs.
* bssid xx:xx:xx:xx:xx:xx -- set the desired BSSID of an 802.11
interface.
* -bssid -- unset the desired BSSID of an 802.11 interface, so
the interface will choose automatically (default).
* channel x -- set the channel (radio frequency) of an 802.11 interface.
Current BSSID and channel are now reported in the 802.11 status
display, if supported by the interface.
Above changes from David Young <dyoung@ojctech.com>, with some slight
changes by me (use ethers(3) functions rather than hand-parsing/printing
the 802.11 address).
