big <utmp.h>-inspired netbsd switch

import/switch of:
init, getty, reboot, halt, shutdown, wall, last

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

-/* getty - get tty speed			Author: Fred van Kempen */
-
-/*
- * GETTY  -     Initialize and serve a login-terminal for INIT.
- *		Also, select the correct speed. The STTY() code
- *		was taken from stty(1).c; which was written by
- *		Andrew S. Tanenbaum.
- *
- * Usage:	getty [speed]
- *
- * Version:	3.4	02/17/90
- *
- * Author:	F. van Kempen, MicroWalt Corporation
- *
- * Modifications:
- *		All the good stuff removed to get a minimal getty, because
- *		many modems don't like all that fancy speed detection stuff.
- *		03/03/91	Kees J. Bot (kjb@cs.vu.nl)
- *
- *		Uname(), termios.  More nonsense removed.  (The result has
- *		only 10% of the original functionality, but a 10x chance of
- *		working.)
- *		12/12/92	Kees J. Bot
- *
- *		Customizable login banner.
- *		11/13/95	Kees J. Bot
- *
- *		Suspend/resume signals removed.
- *		2001-04-04	Kees J. Bot
- *
- *		Removed unused custom banner and returned speed option
- *		functionality (by simply calling stty).

-This a new implementation of a shutdown procedure. It allows 
-the system to go down graciously with informing the
-users. This package contains 3 programs:
-
-- halt = Immediately stop the system, no info to users
-- shutdown = Inform users, close down the system properly
-- wall = Vincent Archer's implementation of wall (Write all)
-
-Installing
-
-Shutdown and halt use a new systemcall, which I've added to
-MM. Therefor there are several diff's which should be applied:
-
-callnr.hd - New callnr for reboot(2)
-	   Diff against /usr/include/minix/callnr.h.
-	   Those of you using a symlink package should
-	   change the number and mm/table.c into a free
-	   number. I used 54, LSTAT.
-param.hd - Defines reboot_flag as a part of the messages
-proto.hd - Add's prototype for do_reboot()
-table.cd - Interpretation of the systemcall to MM
-mm.cd -	   I have added the do_reboot code to mm/getset.c but
-	   I couldn't find a getset.c to create a useable diff :-(
-	   So you can add where you want it. It is pure code, no diff.
-
-Now edit log.c and search for ``host''. Change this into your
-systemname or make it empty.
-
-Shutdown and halt log their actions in /usr/adm/log, edit the
-makefile and undefine -DLOG if you don't want this (this at the end of
-the makefile). You can change SHUT_LOG in shutdown.c and log.c if you
-want it in another file.
-
-Then type a `make'. This will take a minute or so (13 sec. with bcc :-).
-Remember to build a new image and update the ps_database.
-
-Type `make install' to place the program's where I've got them.
-Use them, try them and let me now if you've got problems running
-something.
-
-I have tested to sources both on 16-bits and 32-bits MINIX. I have compiled
-it with gcc, bcc and ACK, so that shouldn't really give a problem. Maybe
-the standard MINIX-make chokes on the makefile, atleast mine did.
-
-NOTE:
-	Make install does not place the man-pages somewhere. You should
-	do this yourself.

+.Oo
+.Ar type
+.Op Ar tty
+.Oc
+.Nm uugetty
+.Oo
+.Ar type
+.Op Ar tty
+.Oc
+.Sh DESCRIPTION
+The
+.Nm
+program
+is called by
+.Xr init 8
+to open and initialize the tty line, read a login name, and invoke
+.Xr login 1 .
+The devices on which to run
+.Nm
+are normally determined by
+.Xr ttys 5 .
+.Pp
+The
+.Nm
+program can also recognize a Point to Point Protocol
+.Pq Tn PPP
+negotiation, and, if the
+.Sy pp
+attribute in
+.Xr gettytab 5
+is set, invoke the program given by that string, e.g.,
+.Xr pppd 8 ,
+instead of
+.Xr login 1 .
+This makes it possible to use a single serial port for either a
+.Qq shell
+account with command line interface, or a
+.Tn PPP
+network link.
+.Pp
+The argument
+.Ar tty
+is the special device file in
+.Pa /dev
+to open for the terminal
+.Po
+for example,
+.Qq ttyh0
+.Pc .
+If there is no argument or the argument is
+.Ql Fl ,
+the tty line is assumed to be open as file descriptor 0.
+.Pp
+The
+.Ar type
+argument can be used to make
+.Nm
+treat the terminal line specially.
+This argument is used as an index into the
+.Xr gettytab 5
+database, to determine the characteristics of the line.
+If there is no argument, or there is no such table, the
+.Em default
+table is used.
+If there is no
+.Pa /etc/gettytab
+a set of system defaults is used.
+If indicated by the table located,
+.Nm
+will clear the terminal screen,
+print a banner heading,
+and prompt for a login name.
+Usually either the banner or the login prompt will include
+the system hostname.
+.Pp
+.Nm
+uses the
+.Xr ttyaction 3
+facility with an action of
+.Qq getty
+and user
+.Qq root
+to execute site-specific commands when it starts.
+.Pp
+Most of the default actions of
+.Nm
+can be circumvented, or modified, by a suitable
+.Xr gettytab 5
+table.
+.Pp
+The
+.Nm
+program can be set to timeout after some interval,
+which will cause dial up lines to hang up
+if the login name is not entered reasonably quickly.
+.Pp
+The
+.Nm uugetty
+program is the same, except that it uses
+.Xr pidlock 3
+to respect the locks in
+.Pa /var/spool/lock
+of processes that dial out on that tty.

+A terminal which is turned on in the

+was not attached during boot-time system configuration,
+or the special file in

+.Nm gettytab
+.Nd terminal configuration data base
+.Sh SYNOPSIS
+.Nm
+.Sh DESCRIPTION
+The
+.Nm
+file
+is a simplified version of the
+.Xr capfile 5
+data base
+used to describe terminal lines.
+The initial terminal login process
+.Xr getty 8
+accesses the
+.Nm
+file each time it starts, allowing simpler
+reconfiguration of terminal characteristics.
+Each entry in the data base
+is used to describe one class of terminals.
+.Pp
+Where to run
+.Xr getty 8
+processes is normally defined by
+.Xr ttys 5 .
+.Pp
+There is a default terminal class,
+.Em default ,
+that is used to set global defaults for all other classes.
+(That is, the
+.Em default
+entry is read, then the entry for the class required
+is used to override particular settings.)
+The
+.Em default
+entry is also normally read by other programs that present login prompts
+to the user, such as
+.Xr telnetd 8 ,
+in order to retrieve the values of the
+.Em he ,
+.Em hn ,
+.Em im ,
+and
+.Em if
+capabilities.
+.Sh CAPABILITIES
+Refer to
+.Xr capfile 5
+for a description of the file layout.
+The
+.Em default

+no entry in the table obtained, nor one in the special
+.Em default
+table.

+.It "uc	bool	false	terminal is known upper case only"
+.El
+.Pp
+If no line speed is specified, speed will not be altered
+from that which prevails when getty is entered.
+Specifying an input or output speed will override
+line speed for stated direction only.
+.Pp
+Terminal modes to be used for the output of the message,
+for input of the login name,
+and to leave the terminal set as upon completion,
+are derived from the boolean flags specified.
+If the derivation should prove inadequate,
+any (or all) of these three may be overridden
+with one of the
+.Em \&c0 ,
+.Em \&c1 ,
+.Em \&c2 ,
+.Em \&i0 ,
+.Em \&i1 ,
+.Em \&i2 ,
+.Em \&l0 ,
+.Em \&l1 ,
+.Em \&l2 ,
+.Em \&o0 ,
+.Em \&o1 ,
+or
+.Em \&o2
+numeric specifications, which can be used to specify
+(usually in octal, with a leading '0')
+the exact values of the flags.
+These flags correspond to the termios
+.Em c_cflag ,
+.Em c_iflag ,
+.Em c_lflag ,
+and
+.Em c_oflag
+fields, respectively.
+Each these sets must be completely specified to be effective.
+The
+.Em \&f0 ,
+.Em \&f1 ,
+and
+.Em \&f2
+are excepted for backwards compatibility with a previous incarnation of
+the TTY sub-system.
+In these flags the bottom 16 bits of the (32 bits) value contain the sgttyb
+.Em sg_flags
+field, while the top 16 bits represent the local mode word.
+.Pp
+Should
+.Xr getty 8
+receive a null character
+(presumed to indicate a line break)
+it will restart using the table indicated by the
+.Em nx
+entry.
+If there is none, it will re-use its original table.
+.Pp
+Delays are specified in milliseconds, the nearest possible
+delay available in the tty driver will be used.
+Should greater certainty be desired, delays
+with values 0, 1, 2, and 3 are interpreted as
+choosing that particular delay algorithm from the driver.
+.Pp
+The
+.Em \&cl
+screen clear string may be preceded by a (decimal) number
+of milliseconds of delay required (a la termcap).
+This delay is simulated by repeated use of the pad character
+.Em \&pc .
+.Pp
+The initial message, and login message,
+.Em \&im
+and
+.Em \&lm
+may include any of the following character sequences, which expand to
+information about the environment in which
+.Xr getty 8
+is running.
+.Pp
+.Bl -tag -width \&%xxx -compact
+.It \&%d
+The current date.
+.It \&%h
+The hostname of the machine, which is normally obtained from the
+system using
+.Xr gethostname 3 ,
+but may also be overridden by the
+.Em \&hn
+table entry.
+In either case it may be edited with the
+.Em \&he
+string.
+A '@' in the
+.Em \&he
+string causes one character from the real hostname to
+be copied to the final hostname.
+A '#' in the
+.Em \&he
+string causes the next character of the real hostname
+to be skipped.
+Each character that
+is neither '@' nor '#' is copied into the final hostname.
+Surplus '@' and '#' characters are ignored.
+.It \&%t
+The tty name.
+.It "\&%m, \&%r, \&%s, \&%v"
+The type of machine, release of the operating system, name of the
+operating system, and version of the kernel, respectively, as
+returned by
+.Xr uname 3 .
+.It \&%%
+A
+.Dq %
+character.
+.El
+.Pp
+When getty execs the login process, given
+in the
+.Em \&lo
+string (usually
+.Dq Pa /usr/bin/login ) ,
+it will have set
+the environment to include the terminal type, as indicated
+by the
+.Em \&tt
+string (if it exists).
+The
+.Em \&ev
+string, can be used to enter additional data into
+the environment.
+It is a list of comma separated strings, each of which
+will presumably be of the form
+.Em name=value .
+.Pp
+If a non-zero timeout is specified, with
+.Em \&to ,
+then getty will exit within the indicated
+number of seconds, either having
+received a login name and passed control
+to
+.Xr login 1 ,
+or having received an alarm signal, and exited.
+This may be useful to hangup dial in lines.
+.Pp
+Output from
+.Xr getty 8
+is even parity unless
+.Em \&op
+or
+.Em \&np
+is specified.
+The
+.Em \&op
+string
+may be specified with
+.Em \&ap
+to allow any parity on input, but generate odd parity output.
+Note: this only applies while getty is being run,
+terminal driver limitations prevent a more complete
+implementation.
+.Xr getty 8
+does not check parity of input characters in
+.Dv RAW
+mode.
+.Pp
+If
+.Em \&pp
+string is specified and a Point to Point Protocol
+.Pq Tn PPP
+link bringup sequence is recognized,
+.Xr getty 8
+will invoke the program referenced by the
+.Em \&pp
+string, e.g.
+.Xr pppd 8 .
+This can be used to handle incoming
+.Tn PPP
+calls.

+.Sh HISTORY
+The
+.Nm
+file format appeared in
+.Bx 4.2 .
+.Sh BUGS
+The special characters (erase, kill, etc.) are reset to system defaults
+by
+.Xr login 1 .
+In
+.Em all
+cases, '#' or '^H' typed in a login name will be treated as
+an erase character, and '@' will be treated as a kill character.
+.Pp
+The delay stuff is a real crock.
+Apart from its general lack of flexibility, some
+of the delay algorithms are not implemented.
+The terminal driver should support sane delay settings.
+.Pp
+The
+.Em \&he
+capability is stupid.

+.Sh NAME
+.Nm ttys
+.Nd terminal initialization information
+.Sh DESCRIPTION
+The file
+.Nm
+contains information that is used by various routines to initialize
+and control the use of terminal special files.
+This information is read with the
+.Xr getttyent 3
+library routines.
+.Pp
+There is one line in the
+.Nm
+file per special device file.
+Fields are separated by tabs and/or spaces.
+Fields comprising more than one word should be enclosed in double
+quotes (``"'').
+Blank lines and comments may appear anywhere in the file; comments
+are delimited by hash marks (``#'') and new lines.
+Any unspecified fields will default to null.
+.Pp
+Each line in
+.Nm
+has the format:
+.Dl tty command type flags
+.Pp
+The first field is the
+name of the terminal special file as it is found in
+.Pa /dev .
+.Pp
+The second field of the file is the command to execute for the line,
+usually
+.Xr getty 8 ,
+which initializes and opens the line, setting the speed, waiting for
+a user name and executing the
+.Xr login 1
+program.
+However, it can be any desired command, for example the start up
+for a window system terminal emulator or some other daemon process,
+and can contain multiple words if quoted.
+.Pp
+The third field is the type of terminal usually connected to that
+tty line, normally the one found in the
+.Xr terminfo 5
+data base file.
+The environment variable
+.Dv TERM
+is initialized with the value by either
+.Xr getty 8
+or
+.Xr login 1 .
+.Pp
+The remaining fields set flags in the
+.Fa ty_status
+entry (see
+.Xr getttyent 3 )
+or specify a window system process that
+.Xr init 8
+will maintain for the terminal line
+or a key into a database of tty attributes (currently unused).
+.Pp
+.Bl -tag -width softcar
+.It Sy on No or Sy off
+.Xr init 8
+should (or should not) execute the command given in the second field.
+.It Sy secure
+If
+.Sy on
+is specified, allows users with a uid of 0
+.Pq e.g. Qq root
+to login on this line.
+.It Sy local
+Sets the
+.Dv TIOCFLAG_CLOCAL
+.Xr tty 4
+flag for the device.
+This will cause the
+.Xr termios 4
+.Dv CLOCAL
+flag to be set on every open and thus modem control signal lines will be
+ignored by default.
+.It Sy softcar
+Causes the driver to ignore hardware carrier on the line (by setting the
+.Dv TIOCFLAG_SOFTCAR
+.Xr tty 4
+flag).
+.It Sy rtscts
+Sets the
+.Dv TIOCFLAG_CRTSCTS
+.Xr tty 4
+flag for the device to enable
+.Tn RTS /
+.Tn CTS
+.Qq hardware
+flow control by default.
+.It Sy mdmbuf
+Sets the
+.Dv TIOCFLAG_MDMBUF
+.Xr tty 4
+flag for the device to enable
+.Tn DTR /
+.Tn DCD
+.Qq hardware
+flow control by default.
+.El
+.Pp
+The flags
+.Qq local ,
+.Qq rtscts ,
+.Qq mdmbuf ,
+and
+.Qq softcar
+modify the default behaviour of the terminal line, and their actions
+are device driver dependent.
+These flag fields should not be quoted.
+.Pp
+The string ``window='' may be followed by a quoted command
+string which
+.Xr init 8
+will execute
+.Em before
+starting the command specified by the second field.
+.Pp
+The string ``class='' may be followed by a quoted string used
+as a key into a database of attributes for that category of tty.
+See
+.Xr getttynam 3
+for more information on this feature.
+.Pp
+After changing the
+.Nm
+file a
+.Dv SIGHUP
+signal can be sent to
+.Xr init 8
+with the command
+.Dq Li "kill \-s HUP 1" .
+On receipt of this signal,
+.Xr init 8
+will re-read the
+.Nm
+file and spawn any necessary
+.Xr getty 8
+processes.
+.Pp
+.Sy Nota Bene :
+Sending
+.Dv SIGHUP
+to
+.Xr init 8
+does
+.Em not
+change the state of the various
+.Xr tty 4
+device flags listed above; the
+.Xr ttyflags 8
+program must be run for changes in those flags to take effect on the devices.

-.TH REBOOT 8
-.SH NAME
-reboot \- reboot the system immediately
-.SH SYNOPSIS
-\fBreboot\fP [\fB\-f\fP]
-.SH DESCRIPTION
-.B Reboot
-can be used to reboot the system after installing a new kernel.  It does
-not inform the users, but does log it's actions in
-.B /usr/adm/wtmp
-and
-.BR /usr/adm/log .
-The system is then rebooted with the
-.BR reboot (2)
-systemcall.
-.PP
-If the
-.B \-f
-flag is not given then all processes are sent terminate
-signals to give them a chance to die peacefully before the
-.B reboot()
-call.
-.PP
-If the wtmp file exists,
-.B reboot
-logs itself as if it were a shutdown.  This is done to prevent
-.BR last (1)
-from talking about system-crashes.
-.B Reboot
-is registered as is in the log file.
-.PP
-.B Reboot
-can only be executed by the super-user.  Any other caller will be
-refused, either by
-.BR reboot (8)
-or by
-.BR reboot (2).
-.SH "SEE ALSO"
-.BR reboot (2),
-.BR shutdown (8),
-.BR halt(8),
-.BR boot (8).
-.SH BUGS
-The error message's given by
-.B reboot
-are not always useful.  There are several routines that can fail, but which
-are not fatal for the program.

+
+POSIX and init:
+--------------
+
+POSIX.1 does not define 'init' but it mentions it in a few places.
+
+B.2.2.2, p205 line 873:
+
+	This is part of the extensive 'job control' glossary entry.
+	This specific reference says that 'init' must by default provide
+	protection from job control signals to jobs it starts --
+	it sets SIGTSTP, SIGTTIN and SIGTTOU to SIG_IGN.
+
+B.2.2.2, p206 line 889:
+
+	Here is a reference to 'vhangup'.  It says, 'POSIX.1 does
+	not specify how controlling terminal access is affected by
+	a user logging out (that is, by a controlling process
+	terminating).'  vhangup() is recognized as one way to handle
+	the problem.  I'm not clear what happens in Reno; I have
+	the impression that when the controlling process terminates,
+	references to the controlling terminal are converted to
+	references to a 'dead' vnode.  I don't know whether vhangup()
+	is required.
+
+B.2.2.2, p206 line 921:
+
+	Orphaned process groups bear indirectly on this issue.  A
+	session leader's process group is considered to be orphaned;
+	that is, it's immune to job control signals from the terminal.
+
+B.2.2.2, p233 line 2055:
+
+	'Historically, the implementation-dependent process that
+	inherits children whose parents have terminated without
+	waiting on them is called "init" and has a process ID of 1.'
+
+	It goes on to note that it used to be the case that 'init'
+	was responsible for sending SIGHUP to the foreground process
+	group of a tty whose controlling process has exited, using
+	vhangup().  It is now the responsibility of the kernel to
+	do this when the controlling process calls _exit().  The
+	kernel is also responsible for sending SIGCONT to stopped
+	process groups that become orphaned.  This is like old BSD
+	but entire process groups are signaled instead of individual
+	processes.
+
+	In general it appears that the kernel now automatically
+	takes care of orphans, relieving 'init' of any responsibility.
+	Specifics are listed on the _exit() page (p50).
+
+On setsid():
+-----------
+
+It appears that neither getty nor login call setsid(), so init must
+do this -- seems reasonable.  B.4.3.2 p 248 implies that this is the
+way that 'init' should work; it says that setsid() should be called
+after forking.
+
+Process group leaders cannot call setsid() -- another reason to
+fork!  Of course setsid() causes the current process to become a
+process group leader, so we can only call setsid() once.  Note that
+the controlling terminal acquires the session leader's process
+group when opened.
+
+Controlling terminals:
+---------------------
+
+B.7.1.1.3 p276: 'POSIX.1 does not specify a mechanism by which to
+allocate a controlling terminal.  This is normally done by a system
+utility (such as 'getty') and is considered ... outside the scope
+of POSIX.1.'  It goes on to say that historically the first open()
+of a tty in a session sets the controlling terminal.  P130 has the
+full details; nothing particularly surprising.
+
+The glossary p12 describes a 'controlling process' as the first
+process in a session that acquires a controlling terminal.  Access
+to the terminal from the session is revoked if the controlling
+process exits (see p50, in the discussion of process termination).
+
+Design notes:
+------------
+
+your generic finite state machine
+we are fascist about which signals we elect to receive,
+	even signals purportedly generated by hardware
+handle fatal errors gracefully if possible (we reboot if we goof!!)
+	if we get a segmentation fault etc., print a message on the console
+	and spin for a while before rebooting
+	(this at least decreases the amount of paper consumed :-)
+apply hysteresis to rapidly exiting gettys
+check wait status of children we reap
+	don't wait for stopped children
+don't use SIGCHILD, it's too expensive
+	but it may close windows and avoid races, sigh
+look for EINTR in case we need to change state
+init is responsible for utmp and wtmp maintenance (ick)
+	maybe now we can consider replacements?  maintain them in parallel
+	init only removes utmp and closes out wtmp entries...
+
+necessary states and state transitions (gleaned from the man page):
+	1: single user shell (with password checking?); on exit, go to 2
+	2: run rc script, on exit 0 check if init.root sysctl != "/", if it
+           differs then fork + chroot into the value of init.root and run
+           /etc/rc inside the chroot: on exit 0, go to 3; on exit N (error),
+           go to 1 (applies also to /etc/rc when init.root == "/")
+	3: read ttys file: on completion, go to 4.  If we did chroot in
+	   state 2, we chroot after forking each getty to the same dir
+	   (init.root is not re-read)
+	4: multi-user operation: on SIGTERM, go to 7; on SIGHUP, go to 5;
+		on SIGTSTP, go to 6
+	5: clean up mode (re-read ttys file, killing off controlling processes
+		on lines that are now 'off', starting them on lines newly 'on')
+		on completion, go to 4
+	6: boring mode (no new sessions); signals as in 4
+	7: death: send SIGHUP to all controlling processes, reap for 30 seconds,
+		then go to 1 (warn if not all processes died, i.e. wait blocks)
+Given the -s flag, we start at state 1; otherwise state 2

+.Sh NAME
+.Nm init
+.Nd process control initialization
+.Sh SYNOPSIS
+.Nm
+.Sh DESCRIPTION
+The
+.Nm
+program is the last stage of the boot process (after the kernel loads
+and initializes all the devices).
+It normally begins multi-user operation.
+.Pp
+The following table describes the state machine used by
+.Nm :
+.Bl -enum
+.It
+Single user shell.
+.Nm
+may be passed
+.Fl s
+from the boot program to prevent the system from going multi-user and
+to instead execute a single user shell without starting the normal
+daemons.
+If the kernel is in a secure mode,
+.Nm
+will downgrade it to securelevel 0 (insecure mode).
+The system is then quiescent for maintenance work and may
+later be made to go to state 2 (multi-user) by exiting the single-user
+shell (with ^D).
+.It
+Multi-user boot (default operation).
+Executes
+.Pa /etc/rc
+(see
+.Xr rc 8 ) .
+If this was the first state entered (as opposed to entering here after
+state 1), then
+.Pa /etc/rc
+will be invoked with its first argument being
+.Sq autoboot .
+If
+.Pa /etc/rc
+exits with a non-zero (error) exit code, commence single user
+operation by giving the super-user a shell on the console by going
+to state 1 (single user).
+Otherwise, proceed to state 3.
+.Pp
+If value of the
+.Dq init.root
+sysctl node is not equal to
+.Pa /
+at this point, the
+.Pa /etc/rc
+process will be run inside a
+.Xr chroot 2
+indicated by sysctl with the same error handling as above.
+.Pp
+If the administrator has not set the security level to \-1
+to indicate that the kernel should not run multiuser in secure
+mode, and the
+.Pa /etc/rc
+script has not set a higher level of security
+than level 1, then
+.Nm
+will put the kernel into securelevel mode 1.
+See
+.Xr rc.conf 5
+and
+.Xr secmodel_securelevel 9
+for more information.
+.It
+Set up ttys as specified in
+.Xr ttys 5 .
+See below for more information.
+On completion, continue to state 4.
+If we did chroot in state 2, each
+.Xr getty 8
+process will be run in the same
+.Xr chroot 2
+path as in 2 (that is, the value of
+.Dq init.root
+sysctl is not re-read).
+.It
+Multi-user operation.
+Depending upon the signal received, change state appropriately;
+on
+.Dv SIGTERM ,
+go to state 7;
+on
+.Dv SIGHUP ,
+go to state 5;
+on
+.Dv SIGTSTP ,
+go to state 6.
+.It
+Clean-up mode; re-read
+.Xr ttys 5 ,
+killing off the controlling processes on lines that are now
+.Sq off ,
+and starting processes that are newly
+.Sq on .
+On completion, go to state 4.
+.It
+.Sq Boring
+mode; no new sessions.
+Signals as per state 4.
+.It
+Shutdown mode.
+Send
+.Dv SIGHUP
+to all controlling processes, reap the processes for 30 seconds,
+and then go to state 1 (single user); warning if not all the processes died.
+.El
+.Pp
+If the
+.Sq console
+entry in the
+.Xr ttys 5
+file is marked
+.Dq insecure ,
+then
+.Nm
+will require that the superuser password be
+entered before the system will start a single-user shell.
+The password check is skipped if the
+.Sq console
+is marked as
+.Dq secure .
+.Pp
+It should be noted that while
+.Nm
+has the ability to start multi-user operation inside a
+.Xr chroot 2
+environment, the
+.Nm
+process itself will always run in the
+.Dq original root directory .
+This also implies that single-user mode is always started in the original
+root, giving the possibility to create multi-user sessions in different
+root directories over time.
+The
+.Dq init.root
+sysctl node is fabricated by
+.Nm
+at startup and re-created any time it's found to be missing.
+Type of the node is string capable of holding full pathname, and
+is only accessible by the superuser (unless explicitly destroyed
+and re-created with different specification).
+.Pp
+In multi-user operation,
+.Nm
+maintains
+processes for the terminal ports found in the file
+.Xr ttys 5 .
+.Nm
+reads this file, and executes the command found in the second field.
+This command is usually
+.Xr getty 8 ;
+it opens and initializes the tty line and executes the
+.Xr login 1
+program.
+The
+.Xr login 1
+program, when a valid user logs in, executes a shell for that user.
+When this shell dies, either because the user logged out or an
+abnormal termination occurred (a signal), the
+.Nm
+program wakes up, deletes the user from the
+.Xr utmp 5
+and
+.Xr utmpx 5
+files of current users and records the logout in the
+.Xr wtmp 5
+and
+.Xr wtmpx 5
+files.
+The cycle is
+then restarted by
+.Nm
+executing a new
+.Xr getty 8
+for the line.
+.Pp
+Line status (on, off, secure, getty, or window information)
+may be changed in the
+.Xr ttys 5
+file without a reboot by sending the signal
+.Dv SIGHUP
+to
+.Nm
+with the command
+.Dq Li "kill \-s HUP 1" .
+This is referenced in the table above as state 5.
+On receipt of this signal,
+.Nm
+re-reads the
+.Xr ttys 5
+file.
+When a line is turned off in
+.Xr ttys 5 ,
+.Nm
+will send a
+.Dv SIGHUP
+signal to the controlling process
+for the session associated with the line.
+For any lines that were previously turned off in the
+.Xr ttys 5
+file and are now on,
+.Nm
+executes a new
+.Xr getty 8
+to enable a new login.
+If the getty or window field for a line is changed,
+the change takes effect at the end of the current
+login session (e.g., the next time
+.Nm
+starts a process on the line).
+If a line is commented out or deleted from
+.Xr ttys 5 ,
+.Nm
+will not do anything at all to that line.
+However, it will complain that the relationship between lines
+in the
+.Xr ttys 5
+file and records in the
+.Xr utmp 5
+file is out of sync,
+so this practice is not recommended.
+.Pp
+.Nm
+will terminate multi-user operations and resume single-user mode
+if sent a terminate
+.Pq Dv TERM
+signal, for example,
+.Dq Li "kill \-s TERM 1" .
+If there are processes outstanding that are deadlocked (because of
+hardware or software failure),
+.Nm
+will not wait for them all to die (which might take forever), but
+will time out after 30 seconds and print a warning message.
+.Pp
+.Nm
+will cease creating new
+.Xr getty 8 Ns 's
+and allow the system to slowly die away, if it is sent a terminal stop
+.Pq Dv TSTP
+signal, i.e.
+.Dq Li "kill \-s TSTP 1" .
+A later hangup will resume full
+multi-user operations, or a terminate will start a single user shell.
+This hook is used by
+.Xr reboot 8
+and
+.Xr halt 8 .
+.Pp
+The role of
+.Nm
+is so critical that if it dies, the system will reboot itself
+automatically.
+If, at bootstrap time, the
+.Nm
+process cannot be located, or exits during its initialisation,
+the system will panic with the message
+.Dq panic: init died (signal %d, exit %d) .
+.Pp
+If
+.Pa /dev/console
+does not exist,
+.Nm
+will cd to
+.Pa /dev
+and run
+.Dq Li "MAKEDEV -MM init" .
+.Xr MAKEDEV 8
+will use
+.Xr mount_tmpfs 8
+or
+.Xr mount_mfs 8
+to create a memory file system mounted over
+.Pa /dev
+that contains the standard devices considered necessary to boot the system.
+.Sh FILES
+.Bl -tag -width /var/log/wtmp{,x} -compact

+System console device.

+.Sh DIAGNOSTICS
+.Bl -diag
+.It "getty repeating too quickly on port %s, sleeping"
+A process being started to service a line is exiting quickly
+each time it is started.
+This is often caused by a ringing or noisy terminal line.
+.Em "Init will sleep for 10 seconds" ,
+.Em "then continue trying to start the process" .
+.Pp
+.It "some processes would not die; ps axl advised."
+A process is hung and could not be killed when the system was
+shutting down.
+This condition is usually caused by a process that is stuck in a
+device driver because of a persistent device error condition.

+.Dt REBOOT 8
+.Os
+.Sh NAME
+.Nm reboot ,
+.Nm poweroff ,
+.Nm halt
+.Nd restarting, powering down and stopping the system
+.Sh SYNOPSIS
+.Nm halt
+.Op Fl dlnpqvxz
+.Nm poweroff
+.Op Fl dlnqvxz
+.Nm
+.Op Fl dlnqvxz
+.Op Ar arg ...
+.Sh DESCRIPTION
+The
+.Nm poweroff ,
+.Nm halt
+and
+.Nm
+utilities flush the file system cache to disk, send all running processes
+a
+.Dv SIGTERM ,
+wait for up to 30 seconds for them to die, send a
+.Dv SIGKILL
+to the survivors and, respectively, power down, halt or restart the system.
+The action is logged, including entering a shutdown record into the login
+accounting file and sending a message via
+.Xr syslog 3 .
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl d
+Create a dump before halting or restarting.
+This option is useful for debugging system dump procedures or
+capturing the state of a corrupted or misbehaving system.
+.It Fl l
+Suppress sending a message via
+.Xr syslog 3
+before halting or restarting.
+.It Fl n
+Do not flush the file system cache.
+This option should be used with extreme caution.
+It can be used if a disk or a processor is on fire.
+.It Fl p
+Attempt to powerdown the system.
+If the powerdown fails, or the system does not support
+software powerdown, the system will halt.
+This option is only valid for
+.Nm halt .
+.It Fl v
+To enable verbose messages on the console, pass the
+.Xr boothowto 9
+flag
+.Dv AB_VERBOSE
+to
+.Xr reboot 2 .
+.It Fl x
+To enable debugging messages on the console, pass the
+.Xr boothowto 9
+flag
+.Dv AB_DEBUG
+to
+.Xr reboot 2 .
+.It Fl z
+To silence some shutdown messages on the console, pass the
+.Xr boothowto 9
+flag
+.Dv AB_SILENT
+to
+.Xr reboot 2 .
+.It Fl q
+Do not give processes a chance to shut down before halting or restarting.
+This option should not normally be used.
+.El
+.Pp
+If there are any arguments passed to
+.Nm reboot
+they are concatenated with spaces and passed as
+.Fa bootstr
+to the
+.Xr reboot 2
+system call.
+The string is passed to the firmware on platforms that support it.
+.Pp
+Normally, the
+.Xr shutdown 8
+utility is used when the system needs to be halted or restarted, giving
+users advance warning of their impending doom.
+.Sh SEE ALSO
+.Xr reboot 2 ,
+.Xr syslog 3 ,
+.Xr utmp 5 ,
+.Xr boot 8 ,
+.Xr init 8 ,
+.Xr rescue 8 ,
+.Xr shutdown 8 ,
+.Xr sync 8
+.Sh HISTORY
+A
+.Nm
+command appeared in
+.At v6 .
+.Pp
+The
+.Nm poweroff
+command first appeared in
+.Nx 1.5 .
+.Sh CAVEATS
+Once the command has begun its work, stopping it before it completes
+will probably result in a system so crippled it must be
+physically reset.
+To prevent premature termination, the command
+blocks many signals early in its execution.
+However, nothing can defend against deliberate attempts to evade this.
+.Pp
+This command will stop the system without running any
+.Xr shutdown 8
+scripts.
+Amongst other things, this means that swapping will not be
+disabled so that
+.Xr raid 4
+can shutdown cleanly.
+You should normally use
+.Xr shutdown 8
+unless you are running in single user mode.
+.Sh BUGS
+The single user shell will ignore the
+.Dv SIGTERM
+signal.
+To avoid waiting for the timeout when
+rebooting or halting from the single user shell, you have to
+.Ic exec reboot
+or
+.Ic exec halt .

+.Sh SYNOPSIS
+.Nm
+.Op Fl Ddfhknprvxz
+.Op Fl b Ar bootstr
+.Ar time
+.Op Ar message ... | Ar -
+.Sh DESCRIPTION
+.Nm
+provides an automated shutdown procedure for super-users
+to nicely notify users when the system is shutting down,
+saving them from system administrators, hackers, and gurus, who
+would otherwise not bother with such niceties.
+.Pp
+Available friendlinesses:
+.Bl -tag -width bootstr
+.It Fl b Ar bootstr
+The given
+.Ar bootstr
+is passed to
+.Xr reboot 8
+for the benefit of those systems that can pass boot arguments to the
+firmware.
+Currently, this only affects sun3 and sparc machines.
+.It Fl d
+.Nm
+will pass the
+.Fl d
+flag to
+.Xr reboot 8
+or
+.Xr halt 8
+to request a kernel core dump.
+If neither the
+.Fl h
+or
+.Fl r
+flags are specified, then
+.Fl d
+also implies
+.Fl r .
+.It Fl f
+.Nm
+arranges, in the manner of
+.Xr fastboot 8 ,
+for the file systems
+.Em not to be
+checked on reboot.
+.It Fl h
+The system is halted at the specified
+.Ar time ,
+using
+.Xr halt 8 .
+.It Fl k
+Kick everybody off.
+The
+.Fl k
+option
+does not actually halt the system, but leaves the
+system multi-user with logins disabled (for all but super-user).
+.It Fl n
+Prevent the normal
+.Xr sync 2
+before stopping.
+.It Fl p
+The system is powered down at the specified
+.Ar time ,
+using
+.Xr poweroff 8 .
+If the powerdown fails, or the system does not support software powerdown,
+the system will simply halt instead.
+.It Fl r
+The system is rebooted at the specified
+.Ar time ,
+using
+.Xr reboot 8 .
+.It Fl v
+To enable verbose messages on the console, pass
+.Fl v
+to
+.Xr reboot 8
+or
+.Xr halt 8 .
+.It Fl x
+To enable debugging messages on the console, pass
+.Fl x
+to
+.Xr reboot 8
+or
+.Xr halt 8 .
+.It Fl z
+To silence some shutdown messages on the console, pass
+.Fl z
+to
+.Xr reboot 8
+or
+.Xr halt 8 .
+.It Fl D
+Prevents
+.Nm
+from detaching from the tty with
+.Xr fork 2 Ns /
+.Xr exit 3 .
+.It Ar time
+.Ar Time
+is the time at which
+.Nm
+will bring the system down and
+may be the word
+.Ar now
+or a future time in one of two formats:
+.Ar +number ,
+or
+.Ar [[[[[cc]yy]mm]dd]hh]mm ,
+where the century, year, month, day, and hour may be defaulted
+to the current system values.
+The first form brings the system down
+.Ar number
+minutes from the current time; the second brings the system down at the
+absolute time specified.
+If the century is not specified, it defaults to 1900 for years between 69
+and 99, or 2000 for years between 0 and 68.
+A leading zero in the
+.Dq yy
+value is
+.Em not
+optional.
+.It Ar message ...
+Any other arguments comprise the warning message that is broadcast
+to users currently logged into the system.
+.It Ar -
+If
+.Ar -
+is supplied as the only argument after the time, the warning message is read
+from the standard input.
+.El
+.Sh BEHAVIOR
+.Pp
+At intervals, becoming more frequent as apocalypse approaches
+and starting at ten hours before shutdown, warning messages are displayed
+on the terminals of all users logged in.
+Five minutes before shutdown, or immediately if shutdown is in less
+than 5 minutes, logins are disabled by creating
+.Pa /etc/nologin
+and copying the warning message there.
+If this file exists when a user attempts to log in,
+.Xr login 1
+prints its contents and exits.
+The file is removed just before
+.Nm
+exits.
+.Pp
+At shutdown time, a message is written in the system log containing the
+time of shutdown, who initiated the shutdown, and the reason.
+Next a message is printed announcing the start of the system shutdown hooks.
+Then the shutdown hooks in
+.Pa /etc/rc.shutdown
+are run, and a message is printed indicating that they have completed.
+After a short delay,
+.Nm
+runs
+.Xr halt 8
+or
+.Xr reboot 8 ,
+or sends a terminate
+signal to
+.Xr init 8
+to bring the system down to single-user mode, depending on the choice
+of options.
+.Pp
+The time of the shutdown and the warning message are placed in
+.Pa /etc/nologin
+and should be used to tell the users why the system is
+going down, when it will be back up, and to share any other pertinent
+information.

+.Sh NAME
+.Nm last
+.Nd indicate last logins of users and ttys
+.Sh SYNOPSIS
+.Nm
+.Op Fl Ns Ar n
+.Op Fl nTx
+.Op Fl f Ar file
+.Op Fl H Ar hostsize
+.Op Fl h Ar host
+.Op Fl L Ar linesize
+.Op Fl N Ar namesize
+.Op Fl t Ar tty
+.Op user ...
+.Sh DESCRIPTION
+.Nm
+will list the sessions of specified
+.Ar users ,
+.Ar ttys ,
+and
+.Ar hosts ,
+in reverse time order.
+Each line of output contains
+the user name, the tty from which the session was conducted, any
+hostname, the start and stop times for the session, and the duration
+of the session.
+If the session is still continuing or was cut short by
+a crash or shutdown,
+.Nm
+will so indicate.
+.Pp
+The following options are available:
+.Pp
+.Bl -tag -width xHxhostsizexx
+.It Fl Ar n
+Limits the report to
+.Ar n
+lines.
+.It Fl f Ar file
+.Nm
+reads the file
+.Ar file
+instead of the default,
+.Pa /var/log/wtmpx
+or
+.Pa /var/log/wtmp .
+If the file ends with
+.Sq x ,
+it is treated as a
+.Xr utmpx 5
+format file, else it is treated as a
+.Xr utmp 5
+format file.
+If the file is ``-'', standard input is used.
+.It Fl H Ar hostsize
+Use the provided hostsize as the width to format the host name field.
+.It Fl h Ar host
+.Ar Host
+names may be names or internet numbers.
+.It Fl L Ar linesize
+Use the provided linesize as the width to format the tty field.
+.It Fl N Ar namesize
+Use the provided namesize as the width to format the login name field.
+.It Fl n
+Print host addresses numerically.
+This option works only on
+.Xr wtmpx 5
+entries,
+and prints nothing on
+.Xr wtmp 5
+entries.
+.It Fl T
+Display better time information, including the year and seconds.
+.It Fl t Ar tty
+Specify the
+.Ar tty .
+Tty names may be given fully or abbreviated, for example,
+.Dq Li "last -t 03"
+is equivalent to
+.Dq Li "last -t tty03" .
+.It Fl x
+Assume that the file given is in
+.Xr wtmpx 5
+format, even if the filename does not end with an
+.Sq x .
+Also useful when reading such format from standard input.
+.El
+.Pp
+If multiple arguments are given, the information which applies to any of the
+arguments is printed, e.g.,
+.Dq Li "last root -t console"
+would list all of
+.Dq Li root Ns 's
+sessions as well as all sessions on the console terminal.
+If no users, hostnames, or terminals are specified,
+.Nm
+prints a record of all logins and logouts.
+.Pp
+The pseudo-user
+.Ar reboot
+logs in at reboots of the system, thus
+.Dq Li last reboot
+will give an indication of mean time between reboot.
+.Pp
+If
+.Nm
+is interrupted, it indicates to what date the search has progressed.
+If interrupted with a quit signal
+.Nm
+indicates how far the search has progressed and then continues.
+.Sh FILES
+.Bl -tag -width /var/log/wtmpx -compact
